I didn't see a way to find out what the original max period value was, either by calling a function or looking at wpilib src code.

that was it. tried it again, turns out that the getPeriod method only consistently gives a reading when our wheel is spinning more than 1200 rpm. anything below that we get either an "infinity" reading or an occasional reading when approaching 1200 rpm. thanks!
