I agree with Jo that, in general, that plot looks OK. That said, I'd use more iterations, e.g. use the max (10) and then the limit of ~20 pixel travel should kick in. Calibrating with under 10 pixels of travel is probably not that reliable.

Also, make sure your scope is close to balanced.

Though the dec-swap option will affect you if you store and re-use calibrations, it should not affect the calibration routine itself, as it just walks one way then walks the other way. It also shouldn't affect you if you re-calibrate everytime, as the calibration routine will determine the correct setting for that checkmark for the current position.
