Could a log be generated to Log the temperature when an autofocus is Done. This would be make it easy to calculate the steps per C to use between autofocuses
I recommend you to download and install Mikael’s SGP AF LogViewer, https://forum.sequencegeneratorpro.com/t/sgp-af-logviewer-v1-2-release/ . The current version is v1.25.
SGP AF LogViewer analyzes SGP logfiles. It generates a table of focus runs with focus position, HFD, temperature, filter, and the characteristic value of focus quality. The software plots HFD versus focus position for each focus run. For each filter that was used, it computes the temperature coefficient and correlation coefficient, and it plots HFD versus temperature.
