Toilet bowling even after decent calibration / offsets. why?

Makes me nervous when I see my quad slowly going in a circle [ toilet bowling ]. 20 sats and about 1 hdop. Is there something I should be concerned about? Is it worthwhile to simply do a compass recalibration every so often? Thx

I did a motor compensation and it fixed the issue completely :smiley:
