First set the two values that will gradually equalize. Then press start and watch the balance shaft. if scratch were accurate to infinite decimal places, one would see that the two values will never reach start 1 = 50 and start 2 = 50. But since scratch is not that precise, you will see start 1 = 50 and start 2 = 50 at some point.
It just occurred to me. 30 minutes to program
