Gary, you are right, temperature compensation is not working correct in SGP - and this is not a missing feature but a bug. With this bug unfixed it is not at all advisable to use temperature compensation, which is a feature that was advertised already for v2 of SGP.
Yes, it’s time for fixing this. The correct algorithm was given here: Temperature Compensation Implementation - Auto Focus - Main Sequence Software
