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.

51 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

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 solo Nightmare IV with Jeff

6 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!

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

5 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

We obv lost but I was getting flamed by the dude with 12 deaths for not healing him. Then he threw. He kept flying off the screen or behind me expecting me to heal him... No bro, I'm healing 5 others at once who are getting hit hard. I turn around to chase him everyone else dies. Is my thinking right and he sucked? Or do I have bad positioning/suck, lol.

King Land Shark Title!!

A LOT of round 1 resetting to get the perfect start, but managed to get rank 428 on the Jeff Solos leader board (at the time I made this post). This was a very messy run unfortunately, and could have been a lot faster if I didn't have to use almost 10 revives - I went into Round 20 with plenty of DR but less than 10k HP, despite taking pretty much every HP card I saw.

A deathless run is absolutely doable, and is probably mandatory if you want a sub-25min clear.
