OK I get it now. The internal 1ms resolution timer keeps track of the elapsed time since the PID was last executed, and uses that elapsed time for the computation (derivative & integration) for the current iteration? So the elapsed time used for the computation can (will) be different (due to jitter) from iteration to iteration?
