What is new about this? We talked several months earlier about that team smurf elo boost exploit.
It’s only viable cause we still have the wrong calc for team elo. It has to be the exponential average @Mercy9545 proposed like 2 years ago or so.
Elo is a logarithmic projection of the strength distribution, that means if you want to “add up” you have to use the correct methods for logarithmic functions we learned in school. That’s all.
A) Log(10) + log(10) = 2, but log(10 + 10) = log(20) ~= 1.3
B) log(1) + log(100) = 2, but log(1+100) = log(101) ~= 2
And that’s what is abused with the showed method. On the left side is the wrong current calc and on the right side how it should be calced.
Explanation: Team A as 2 members with the same elo whilst team B has two with different elo. The current system says they are “evenly matched” but it’s actually wrong, Team B is way stronger than team A cause the current calculation method underestimates stronger players and overestimates weaker playsers impact.
