besenyeimI didn't post this screenshot previously (didn't seem important), but it shows the problem with high speed.
I set higher frequency scanning and spun the thing by hand with a speed that's unusually fast for a knob. The graph shows how the rotor slows down after that. Note how the pattern is changing by time. Not just amplitude but the shape too. The EMF distorts the signal so much, my simple algorithm can't recognize the changes. That's why I mentioned in the project details that an advanced method is needed for this case.
