tested some stuff today, I havent timed any of it

1. dropping down there and jumping across saves spending time doing 2 climbs.
2. jump over boxes and (I think) you'll guarantee the fast climb animation. There are...three? spots you can do this in.

AHITH magic jump. harder with frame limiter on (this video was with it off) but possible. Runnerhaworth says he thinks he found a semi-consistent spot for it so I hope he'll chime in with that

For that 2nd video, I normally do this instead

It's a lot easier to do that jump then it is to quickly jump down to that second level and jump over. Seems faster too. The jumping over the box thing seems cool though

ah, I screwed up that top left jump every time I tried it, so I thought it wasn't possible actually. Your top left route would be even faster if jumping over the crate on the second jump too, causing the faster climb animation

Josh's jump is aids, this is better

I decided not to try to make the clip to the roof more consistent when I found that it only saves ~2s.

One big climb and multiple small climbs take equally long (under 200ms difference, so I can't tell). I compared one big climb to small climbs that use the very small things (are they called packages?) and the ones of middle size. Therefore, don't go out of your way to do multiple small climbs.

Getting armour costs ~8.5s compared to skipping it when using the route without climbing. The quick and dirty climbing timing showed a four seconds difference.

The "quick big climbs" happen based on distance, I found a couple of reference points. You need a media player supporting subtitles since they contain the relevant things. In VLC, press V to enable them or use the menu (Subtitles -> Sub Track).

It is incomplete, maybe one of you feels like completing it. ^^ Else, I will, in a week. Maybe.
