There is an Error in the calculation of the new_rotation_distance in the Tuning Chapter Extruder Calibration

Hey, I think there must be an error in the calculation of the new rotation distance. There is a difference between the calculations of Klipper Marlin and RepRapFirmware. I dont know if this is intended, but I just wanted to make sure, that it is correct or gets corrected.
