Can please someone link this crucial information to the devs about Elo:

Elo is a **logarithmic projection** of the **strength distribution**. That means, that if you want to add elos, you have to use the correct **addition method** for logarithmic functions.

How this works is described [here](https://forums.ageofempires.com/t/smurf-must-be-stopped/196610/57) .

And how you can practically implement is described [here](https://forums.ageofempires.com/t/smurf-must-be-stopped/196610/64).

The basic concept was proposed by @Mercy9545 years ago [here](https://forums.ageofempires.com/t/analyses-of-the-ratings-spotting-the-issues/81949/93)

Every attempt to add up elos in different ways like just directly adding them up is **doomed**. It won’t work, cause it ignores the basic mathematical properties of the elo system.
