I don't check ascension much but has anyone checked to see if this jump was possible? I've done it like 7 times now so I was wondering if I found something new or not. (I'm only asking cus it seems like it could be relevant and the World record didnt exactly have just a clean jump across without the human board).

Yes, this jump is possible although it is incredibly difficult. However, it is much easier to jump on the head of the humanboard to jump across and the difference is time is minimal if it is performed well.

here's a video example:

Ok, thank you!!
