Did you ask the FPGA for the elapsed time (using the microtimer) between the last two counts ?
The latter (via GetPeriod()). The issue was that the FPGA declared the motor stalled below certain speeds. We considered the other method for a bit, but decided that it wasn't really necessary to implement since the problematic speeds were so slow that the ball wouldn't even get out of the shooter.
