Yes, that is the resolution. I can't get any data between those increments.
(By the way, there's 10,000 points of data on these graphs. They're in power increments of 1/1000, with 10 samples at each increment)
The data in these graphs have not been processed, aside from scaling speed to account for the gearbox ratio and encoder placement.
If you're talking about the second motor, yes there is a change in sound, but it's a lot harder to hear because there's no sudden change.
