There's room for improvement like better movement and aiming. 1:24 flat or sub 24 is definitely possible.

00:01.201 - Run starts (last dark frame) 00:33.868 - Load 1 starts (iDroid screen disappears) 00:38.167 - Load 1 resume (last dark frame) 01:02.134 - Load 2 starts (cutscene starts / camera angle changes) 01:05.167 - Load 2 resume (last dark frame) 01:32.117 - Run ends (fulton icon disappears)

If there's something wrong with my timing I'll fix it as soon as possible.
