Hi-
That looks good and as long as it is consistent you may be ok. You can set the backlash compensation to be as large as you want. It has no direct connection to the width of the focus curve. At the start of autofocus the backlash compensation will cause the focuser to go to very high numbers and then come back down to take the curve. When you don't have enough backlash compensation, the curve will do weird things and won't be repeatable. But once you go out far enough to the right and then come back in to take the curve - it should behave well.
Unfortunately SGP only takes the curve from high numbers to low - so changing the meaning if "In" and "Out" directions has no effect on the curve. But you do have to set the backlash direction properly so it only happens when you go to a higher number - and not during the focus curve when all steps are to a lower number.
I'm still not clear if the curve is being taken while the knob is turning counter-clockwise. If it is clockwise, that may explain the shift you are seeing, and the focus may not hold as well as if it were ccw. But you may be ok. The curve certainly looks good.
