Ah forgive me, pre-coffee me wasn’t understanding fully what you did there. 😃

LGTM

Haha, no worries 😉. It’s also rather complex topic. I am also no mathemetician, so programming this stuff and explaining is also no easy task for me. The linear strategy also has the calibration table (multiple calibration values) and other variables to account for, so it was a lot of work to get it right. But I’m pretty sure I have got it right now. Did a lot of testing with different scenarios.
