I lost a lap in similar fashion in that F167 race as well.
Yes, but as you finished behind GT in that race then you also didn't loose any places
Giving laps back takes about 5-10 minutes per incident now I have the templates, the original template took an hour or more of research and testing before it worked well enough to trust.
As I said, if positions/points aren't affected then I'm not spending an evening in spreadsheet-land for no reason
Anyway, the calculations seem in order and I even copied and inserted the edits without mucking up by the look of things - huzzar!
