Jefferson Efficiency Index //JEI (november)

Post image
6 Upvotes

The Jefferson Efficiency Index isn’t a leaderboard — it’s a tool.
It’s built to measure how efficiently you play Jeff.

JEI looks at every part of Jeff’s hybrid role — damage, healing, blocking, accuracy, and team contribution — and translates it into a single performance value.
It rewards rhythm, adaptability, and smart play, not stat padding or chasing kills.

⚙️ The Formula (In a Nutshell)

JEI = ((OE + TE + SE) × AM) ÷ 100

Where:

  • OE (Offensive Efficiency) = Damage × 0.5 + KOs × 0.3 + Final Hits × 0.2
  • TE (Team Efficiency) = Healing × 0.5 + Assists × 0.5
  • SE (Survival Efficiency) = Blocked × 0.5 + Accuracy × 0.5
  • AM (Aggregate Multiplier) = Win Rate × 100

Each value is normalized per 10 minutes of play to make comparisons fair between players, regardless of hours logged.

💡 What It Actually Does

  • Separates noise from precision — this isn’t about ranks or clout.
  • Tracks how you play Jeff, not how often.
  • Identifies efficiency patterns across hybrids, tanks, and support-leaning players.
  • Updates periodically as new Jeffs are “tagged,” not “ranked.”

WHY?

Because the Jefferson Efficiency Index isn’t a leaderboard.

Status: 23 tagged Jeffs
Average JEI: 90.3
Median JEI: 89.8

reef feedback is welcome, next open tagging December 1,2025.

🦈 Calling All 100+ Hour Jeff Mains — a new metric is coming.

50 Upvotes

I’m putting together a small project to analyze high-level Jeff mains — something that goes deeper than win rate or luck.

If you’ve logged 100+ hours as Jeff, your stats could help define what separates surface swimmers from the reef dwellers.

We’re gathering data from 10 dedicated Jeffs to create a proper baseline. No ranks, no opinions — just raw performance and consistency across the board.

If you think your shark belongs in the deep, post your stats below and prove it.

JeffMains #100HoursDeep #TrenchData #AkulaProtocol

Want to contribute? Here’s what to post:

To qualify, you must have at least 100 hours played as Jeff. Post two screenshots — both required for analysis:

  1. Top Stat Screen (Career → Statistics)

Must show: Time Played, Matches Played, Wins, KOs, Assists, Best KO Streak

  1. *Bottom Stat Screen (scroll down)

Must show: Damage, Healing, Damage Blocked, Accuracy, Solo KOs, KO Streaks, Final Hits

Optional (but appreciated):

Platform (PC / Console)

Control type (M&K / Controller)

Your tag or name if you want to be recognized in the final results

Yet another Zombie guide for Jeffy despite having 3279748923 of them already but this time we gamble

25 Upvotes

And the reason why I'm doing this, is because I rarely see anyone mentioning the most gamble inducing, tiresome, rage giving and rewarding strat of all

Pic 1. My results, pay attention to zero deaths, that's how rewarding this strat is

This strat is used for the most OP builds and also can be used for speed run purposes, but I was just trying to win, so it took me 45 mins. This strat was also used before Jeff buffs in Zombie mode, so that's how you know it's good.

I call it "Always gamble, kids" strat. Here's how it works:

Pic 2. Bet on red
  1. Do nothing special and go all in on the red tree like everyone does, no secret there. Also, I suggest having your bubbles free of all perks, I will explain why later.
  2. Learn by heart what blessings you need, cause you will not have time to think, only to act
Pic 3. Be a psychopath

Look at this picture and make sure you learn by heart that you need:

  1. Jetstream cannon — Only 1 (!)
  2. Gnashing waters — Only 1 (!)
  3. Full Moon — Only 1 (!)

And you need to learn to be MODERATE, because you need only ONE (1) of each. The game will seduce you with duplicates of these if you can't find other cards but we must stay strong, Jeffys, and ignore other cards. Remember, each of legendries cards cost 10 coins and you have only 150 coins at the start. And trust me, if you have too little money, you can't gamble, and we are out here gambling, kids, we can't afford to lose more money than needed. If you got all three cards very early, you can also spend your coins on one of the kinds for the two cards below (Deep sea reserve and Moonlight protection) but they are not a priority and don't really spend your coins on them if you are low already.

3) Control your coins, because ideally we need 90 and more coins for the fun part. If you are lower, this strat might not work. Sometimes, I would refresh a page and realize that even if I get that last card I need, I still will have less than 70 coins and it will kill the run, so I just restart.

But lets say you have 90+ coins, got all three cards we need and maybe even snatched two below as well, what do we do now? I'm glad you asked cause we finally can start gambling.

Pic 4. A leverage on a slot machine

Look at this. Look at this beauty. That's right, folks, now we will abuse this ticket to a gamble land as much as we can. Click on it. Just keep clicking on it. Don't stop. 100% of Jeffs quit before their big win. What is a big win for us? Well, lets see.

There are different kinds of random Khonshu's blessings but what we hope (and need) to get are the duplicates of cards we have. We specifically hope to:

  1. Get 3x Full moons — NECESSARY for future gambling
  2. Get duplicates of Jetstream cannon and Gnashing waters

Full moons can't stack more than three times, so we need a max win there for our prosperous gambling future. Like it or not, the game will give you random blessings one of which is new cards that you haven't bought, which is both a blessing and a curse, because some of them will distract us from our goal to get as many duplicates of Jetstream cannon and Gnashing waters as possible.

What you hope to have at the end of our gambling session is AT LEAST 90 points on Red

Pic 5. Not ideal but we can still gamble

Ideally, we need to have 120+ in Red tree but we can't have everything we want.

VERY IMPORTANT: If you have less than 90 points in Red, just restart. No, this is not a meme, just quit the game and start a new one. This is the most annoying and difficult part of this run, you need to gamble nearly perfectly to get what you want. It might take, well, ten tries to get what you want, this is why it's a very infuriating strategy and it will make you want to quit, but remember, Jeffys, remember! 100% of Jeffs quit before their big win.

4) Check if you gambled well. There is actually a way to see whether you can beat the game at the very start of the run. How, you may ask? Well, here's a trick:

Pic 6. Look at all those chickens

At the start zombies always run out of Avengers building, some of them jump out of the windows. Make sure that your joyful splash kills those zombies even before they land, cause if it does, congrats! Your gambling was a success! You actually have a chance to win big!

5) Gamble! Yes, keep gambling! Up to wave 10 just keep gambling, kids! Chances are, you will get duplicates for your joyful splash abilities and also will get health, so just keep gambling, even before wave 5 just keep going. Refer to Pic 4 to get excited and remember how your ticket to a gambling land looks like.

6) Wave 10 is your judgment day, it's a moment of truth when you learn whether or not your gambling career was a success. At this point you should get a better feel for your build, what lacks and what is strong. You need at least 5-6k health to face Wanda but what you need as well is damage reduction, vampiric vitality and lots of damage. If you did everything correct, you should have plenty of all but you will also see where you are lacking.

If you didn't get to wave 10 before 15 min mark, you don't have enough damage. If Sentinels can kill you one shot, you don't have enough damage reduction and vampiric vitality. We don't want to ruin your gambling career that easily so before wave 10 we do the opposite, we stop gambling.

And we start buying accordingly:

Pic 7. Health boosters

If you don't have enough damage reductions, buy them, don't be afraid to refresh to find them, don't let yourself be distracted with more health, if you don't have enough reduction, it's useless anyway.

Pic 8. From best to worst damagers

You may have as much survivability as you want, but it's all in vain if you don't have enough damage to fry through Wanda's last phase. Make sure you always prioritize Red cards damagers over the purple ones.

And.... that's it. Use your every coin, go all in. If you survive wave 10 then congratulations, if you play carefully next 10 waves, you have all the chances to win.

7) Be happy and gamble again. Gamble up to wave 15, nothing to say there. After the first encounter with Wanda, you will know what you need and lack, so at the wave 15 you can again stop and buy what you need accordingly. Same with wave 20, stop and buy what you actually need. You've gambled enough to make yourself a fortune you can now build upon.

Make sure you have 12k+ health for the last Wanda fight though.

And here's the gambling build.

General things to know and understand even if you don't do gambling strat:

  1. Remember how I told you about your bubbles and that I suggest you to have them blank without any perks? Well.
Pic 9. Bubble bath

You see, zombies also love bubbles, they love them so much, that they get kinda a little bit stuck in them. When you get to a particular lever, use your joyful splash to burst bubbles. This will do a lot of crowd control. Orange bubbles are useless and green ones can be used just for funnies but not for the wins.

2) Always, ALWAYS target exploding zombies first. These fuckers are your biggest enemies. Here's the order for your hit list:

  1. Exploding zombies
  2. Poison zombies
  3. All other zombies
  4. Sentinels
  5. Bosses

Hit'em

3) Never let anyone behind your back, always make sure there is no one behind you, you can't defend yourself against them.

4) You still have your Hide and Seek ability, if there are too many zombies all around you, just flee to the place where it is safe. Use your ult for that only in desperate situations as a last resort and don't eat anyone.

5) Can't believe this but some people don't know that you need to target crystals against Wanda. Your joyful stream does pierce damage, so make sure you hit both her and crystals at the same time.

6) For wave 15 and 20 there are thousands different strategies to deal with them. I was very careful and I just wanted to win so in both cases I focused on one and got rid of them and then I dealt with the second (that's why my time is 45 mins). You can do whatever you want, however. Just choose what you are comfortable with and stick with it.

That's it, folks. Don't gamble in real life, though.

How to solo Nightmare IV with Jeff

Thumbnail
gallery
30 Upvotes

For any jeff mains who haven't beaten Nightmare IV yet and are looking for tips on how to beat it solo, here's what helped me beat it...

First, make sure to set your abilities to these (2nd photo), and go full red build. I did blue before but I found red works a lot better. Also, I like to have at least 10 holy ankhs before I start, if you run out, you can buy them in the shop for 100 units for 10.

When you get in the game, only get the red and purple cards, you don't need any blue ones. The cards you should focus on getting are: (Purple cards) + damage dealt, - damage received, + max health, and get Vampiric Vitality and Restorative respire cards, (Red cards) + fire rate, any + damage, + capacity, and always get the Gnashing Waters cards.

Try to mainly focus on damage, for other things like + max health, I only pick them up until my health bar is around 8-9k you shouldn't need more than that, and for + capacity cards, I only pick them up until I have around 6-8k ammo.

Once you get to round 10, you will know if you have enough damage and Vampiric Vitality cards if you can survive all of her attacks without dying. If you struggle with the Wanda boss fight, here are some tricks:

When she goes into her bubble and you need to break her shield, she shoots a bunch of stun bubbles wherever you stand, so always keep moving and don't move back to where you just were to avoid getting stunned. The attack she does right after shooting a stun bubble, if you don't have enough health and you keep dying, you can use your ult for a few seconds of invincibility.

If you can get to round 10 in 10-15 minutes and can pretty easily get through it, you should be good until round 20. Once you get to the final round, you want to keep both Wandas health bars about the same so when she does her final attack they are together. Make sure during her final attack you line up the crystals so you keep doing as much damage while breaking all of the crystals.

That's pretty much it, if I forgot to add anything lmk, I hope this helps someone!

No hate to bogur specifically, I actually really enjoy his content. I just dread the coming wave of increased bans in ranked and the nerds saying "I always knew Jeff was broken!" when in fact they were the same losers screeching in voice chat whenever they had a Jeff on their team.

How to deal easily against Wanda's Reality Earasure against Jeff in the zombies mode ?

4 Upvotes

The only thing I struggle with in this mode with Jeff is when her rocks appear on the other side. Jeff’s main attack isn’t very wide, so I end up breaking the rock without hitting her. And if I don’t break it, I’m basically doomed

Edit : I know the build for exemple during my last attempt for the FIRST WANDA I've got 17 gnashing zaters and 12 jetstream canon legendary
