I tested this last year. I tried 800 hz to 10 hz, and everything faster than 100 hz behaves the same way as 100 hz because the victor can only be updated every ~20 ms (50 hz).

Also, I don't think that a drivetrain used in FRC will benefit from being updated 100 times a second vs 1000.

Where did you find the 1000hz number? I'm not saying it's wrong, but I couldn't find it online.
