I will check out the puzzle speed bonus thing. That is annoying.
As for the rating of that other puzzle, those are set by the fail/pass rate of people who have attempted it. We don't manually manipulate them.

Faced this bug before : https://www.chess.com/forum/view/speed-bonus-error
I did puzzle #653064
The target time is 1:03. I solved it in 54 seconds, but got a 97% speed bonus instead of 100%
The tooltip says that a player of that rating should solve it within the target time in order to get 100%. I solved it faster and am way below the rating.
Unrelated, but this one's been bugging me.

It was in a puzzle rush rated 1140. To play the last move you'd have to see that it leads to a forced mate in 6 because if at any point black's king can escape checks, it's checkmate, so that seems quite steep for a 1140 rated puzzle on puzzle rush when the others of that rating are hanging pieces or mate in one or two.
