Yep, this one is known, I couldn't find a setup for it though. It's in this thread under "instance #2". The issue with the earlier one is that you have to dodge all the enemies when you get it, which is why I like the one at the end much more because there are no slowdowns on the way to getting it, though I have not done precise timings of which would be technically faster.

I wasn't sure if I should post it here or in "any more glitches" topic, but since it has to do with airwalking - here's the unusual encounter of the glitch I got during my practice [hence starting from a savestate and rewinding]
