About the rating, the ELO or its variants are only as valid as the playing pool is constant. Otherwise it is subject to inflation/deflation. Besides the percintile of players, it would be nice to have an accuracy associated with the various ratings, ie purchasing power.
So a feature request: somehow show that say given the games of last month, a rating accuracy is X, and that it is different, given the active playing pool, than it was a month ago.
It is really frustrating to get opponents of a rating that all of a sudden means nothing, given that I face a difficulty level -- if, and that is a big if, if the profiles are human and honest, not smurfing nor hansing -- so a difficulty level I have in mind for 2100 not 1550, and indeed the CPLs do say that much.
