How much of a factor can the backcheck play in fast repetition? I've heard that analogy before in Yamaha classes (backcheck wire "spring" sort of = rep lever) and can see some truth to it when you have a long note followed by a very short one. However, I don't think fast repeated notes (drum repetition) are affected by the backcheck.

As the key starts to release the backcheck wire springs back, shoving the hammer forward slightly which allows the jack a milisecond more time to get back under the hammer butt.
