After few Races with AI on time length, I get confused by the countdown. It feels like if the timmer runs 0 just after the leader start a new lap, this lap will became the Final lap. But if time out when leader is well in a lap, there would be a +1 lap. Just wonder if it indeed is the game setting, and what's the line? the S1/S2 or midway or S2/S3 line?
