Loading pauses are manual, so there is a little bit of a difference. Below is the Actual mission finish, and the manual mission finish.

1 - 10:18.49 - 10:18.81 = 00:00:00.32 2 - 16:44.21 - 16:44.52 = 00:00:00.31 3 - 33:01.99 - 33:02.99 = 00:00:01.00 4 - 37:58.32 - 37:58.67 = 00:00:00.35 5 - 46:18.50 - 46:19.92 = 00:00:01.42 6 - 50:57.50 - 50:58.27 = 00:00:00.77 7 - 1:07:12.24 - 1:07:13.29 = 00:00:01.05 8 - 1:12:22.97 - 1:12:23.26 = 00:00:00.29

Total negative = 4.51 seconds (5,51 s) Actual run = 1:12:18.75 (1:12:17,75) (I hope I did my math correctly)
