why does timer starts saying no doesn't it loose 7 seconds on mr incredible movements.

Because RTA is the standard for most speedruns these days and it happened to be the method we chose for this game. The only reason why we don’t use RTA with the original game is because the first runner timed it with SDA so that’s the standard for that game. Also, the first game starts with a long unskippable cutscene which doesn’t really need to be timed whereas this game doesn’t.
