ELO RATING SYSTEM MODIFICATION
We are looking for a way to modify the ELO rating system so that new users have a reduced effect on the rating of established users (but normal effect on theirs).
The GLICKO-2 system has this property but seems overly complex to achieve just this one effect.
If anyone has an understanding of these rating systems and could suggest a way to modify the ELO rating system, then please send it via the feedback form or by email.
