If you click on a game, you can see the time spent on various moves in the notation. Chess.com removed the statistic from people's profiles some time ago.

(I'm sure this has been brought up a billion times already, but a quick search did not reveal anything recent)
So in daily chess, there was a feature that told you how fast you play, in terms of time spent per move. But it was removed some time ago. Why?
It seems the feature still exists - I know that because I tried registering for a tournament with a time per move restriction and I did not qualify. I also know chess.com records the time you spend between moves, although I am not doing the manual calculation.
