Just saw it on youtube :D probably the fastest I saw to that point (including on events).
Well done - I guess :D
We knew about some tricks but the one after the lift-room. We didn't know that far. Most speedrunners we had so far used the cogwheels to jump on (which was fine for us as it is quite tricky to get them placed verticallly - without them rolling away).
Love those videos for bug finding! But looks mostly like collider problems *phew*
