Using Ninco Digital, I had observe, with the pit stop line, next Start-Finish line, and seting that pit stop is a new lap too, the time is taken in Pit In, and if it is far from S/F line, the lap time is not correct.
May be, it could be better if the time, before and after a pit-stop, never is taken as a possible best lap.
Also, the possibility of choose which ( pit in or out ) is near the S/F line, could be a good solution.
Thanks
