Re: Match Length Question

Personally, I believe that this 'issue' isn't something to get upset at, but if the FMS can't time 135 seconds accurate to more than 2.8 seconds, there is something very wrong with how it's written. The hardware is more than capable of doing it more accurately, and it's not impossible to write software that will be more accurate (see cheesy arena).

The Driver station provides this mode (Practice) automatically, so you don't need to write your own (which as you saw has a risk of being accidentally included on the robot!).
