If you are calibrating at high declinations, it will require bigger steps than if you are calibrating at low declinations.
It is moving the mount by intervals of RA, but looking for a result in pixels. Because lines of RA converge towards the poles, it needs to move more RA units to get the same pixel movement. You need to manually make this adjustment or you will get that message.
If you are using ASCOM pulse guiding instead of ST-4 guiding, you can calibrate once near the equator and then re-use the calibration on future targets at different declinations.
