Separate ratings for each time control


I think there are already more than enough ratings. Yes, there are differences between 3 2 and 10 0 but you already have 10 separate ratings, not counting the tactics and lessons "ratings".
Would 20 ratings be enough? 30? Where would it stop?
It might be interesting to be able to sort and query one's archive by time control but there is no need for separate time controls for each permutation of the time control.
