After a pier flip and during recovery, SGP does an auto center, but does not validate and fix the rotation angle. The rotation angle error is listed as “N/A”.
It should check rotation in both cases, as it does during the initial centering. Most mounts are not perfectly orthogonal and after a pier flip the rotation is usually off.
