Hmm, so I finally did it in a speed run, even though there wasn't much speed there <_<
1:53:25
After 5 tries and a ghost (the ghost usually gets me after I fail the SKD once or twice), I got through. Took the camera a long time to reposition itself...
Hit the first check at 41:02, could've easily been a 0:39 one.
Had around 4-5 seconds of mistake in there as well.
I don't know how much the 4 tries and the ghost cost me, I'd guess around 6-7 seconds?
I guess my aim will be sub1:44? Sounds reasonable to me...
Also, Paragod, you should probably upload a video sometime soon, because even if it isn't perfect, there aren't any other good PC speedruns out there to my knowledge, so that would help us all. That'd be nice!
EDIT:
1:49:69
Up to the first check, everything went really good! Idk what my time was, but I think somewhere high 39 or low 40.
After failing once and being held by the ghost, I got through the door on my second try - and that's where I had some really AWFUL mistakes, hence the improvement of only 4 seconds.
-> still, this run was checkpoint-free!
