I missed the sub 1:25 by one very simple yet very big mistake on the 2-3 mission. Completely failed my attempt and almost died in the process. Otherwise, each section was pretty much perfect for what I practiced. It's still possible to gain a few minutes in overall, but I really doubt sub 1:23 is possible.

I really wish I could find a way to do the 3-4 skip at the end rather than wait for the events to unfold, but I couldn't find any way to reproduce bugs that were happening in the PS3 version, even by forcing framerate to 30 and such.
