Since I used the 5 minute Xbox One Capture feature, the first 13 seconds of real time is not recorded but this does not affect the in-game time counter. From clicking USA 1 to the start of the course is 11.15 seconds and the capture starts at 2.345 seconds into USA 1. This 13.5 seconds added to the time of finishing USA 5 at 4:53 is 5:06.5, with an IGT of 3:53.752. Pretty proud of this run, IGT WR.
