I just would like to add to the explanation below that ratings have no meaning-only rating differences. So where the scale is centered is immaterial.
@petri999 said in #6:
> There no such thing as overrated. Ratings are relative i.e meaningful only within pool. Since default starting rating in
chess.com is 1200 and lichess is 1500 this created difference of ratings of about 300 points. Minuscule difference in rating algorithm is pretty meaningless.
