EOMM vs. SBMM - A Case Study by UCLA with the Assistance of Electronic Arts
Every heard of EOMM? It stands for engagement optimized matchmaking, which is different than skill based matchmaking.
This study by UCLA, with the assistance of data provided by four employees of Electronic Arts, the publisher for Respawn Entertainment and Apex Legends, took data from over 36.9 million matches from 1.68 million unique players.
It discusses the EOMM model using variable inputs such as churn rate to optimize player retention, and discusses similarities to SBMM.
In my own conclusion after reading through this, it appears that we actually live in a state of EOMM more than SBMM, but one that employs known SBMM logic and systems, which would explain why you have three excellent games in a row, which appear to be SBMM-related, only to get steamrolled on your fourth, and so on.
Before you comment and rail Respawn, Electronic Arts, or anyone in particular, I suggest you read the length of the paper (8 pages including citations, not a long read at all). I'm posting this here for discussion purposes, not to ignite a fire in the community.
If presented as EOMM versus SBMM, after reading this paper, would you feel better or worse playing under the parameters of this matchmaking algorithm?

This one will probably make you feel unpleasant

Yes and if you read this and have half of a brain, you will also quickly understand that this theory is not applicable for Apex. EOMM is used for 1v1 games where every game have three possible absolute results, win, loss, draw. EA obviously developed this for games like FIFA and MADDEN. People should really stop mentioning EOMM game theories with Apex because that just puts a big clueless sign over your heads. TRUST ME. Its impossible to use the results of the EOMM study in a game of 60 players in 20 teams where you have one winner and 59 losers.
Ofc, the devs implement ways to maximize player retention in various ways, thats just normal for any game, BUT ITS NOT BASED ON EOMM! The only reason why people to this day still blabber about EOMM is because ONE article on Dexerto where they noticed that EA just filed a patent for EOMM algoritms and asked the question "do Apex use this?"; a typical click bait article with no proof what so ever. So once again; please read the study and then explain to me how the EOMM matchmaking algorithms could be used in BR game with 60 players.

Right on, and thank you.
