One rating by variant and by game duration

Dear all,

I think it would be a nice feature to have four kinds of ratings (bullet, blitz , classical, and correspondance) for all variations (chess, chess 960, KOT, etc.).

In this way, all ratings would be significant. Indeed, all variation ratings (not those of chess) may be somewhat irrelevant because they confound several very different durations.

I think that would be too convoluted myself. Just my opinion.

Anything has a cost.

I think it is really a nonsense that a correspondance game in chess 960 has same impact on rating as a bullet game in the same variant.
