Moshe, I am not sure if correcting the start always fixes the issue, although it did for me in few cases, not sure exactly how.
Regardless, one would always check that OLC identified the release correctly and adjust if needed, otherwise this may significantly impact your score.

IIRC you can adjust the selection of the point in time (not the altitude) at which it starts counting the flying as soaring, i.e., off-tow. Usually it does that automatically but sometimes it gets that wrong. E.g., if you release in strong wave lift and just keep on climbing without circling.

But how can that affect the OLC assumptions about your true altitude vs. the recorded altitude? If it makes assumptions about that, it must be based on the earliest "fix", which it assumes is before the start of the launch?

Pilot's responsibility to bring the goods.

Bring defective stuff, don't expect satisfaction.

If OLC "adjusts" the altitudes just because the early data in the flight log is higher than the airport, then I think it should not do that. The fact that the takeoff is missing in the log does not make the rest of it "garbage". It's the OLC web page graphical display that displays "garbage".

Moshe,
Just for interest I can relate that I had a MWN flight to 12,300 last year but OLC showed the max as much lower. But for some reason my flight was broken up into 2 sections in my Nano. I had hit extreme turbulence on tow and I am wondering if that reset the logger somehow. Anyone else notice this problem with a Nano 3?
