I agree with a couple of your points, and the only reason I relied so heavily on tricking was because parkour and sparring while being impressive, either require mods or don’t fall into an account of anything achievable.

Anything that holds a stall record is fairly easy to record. Record the frame the foot leaves the ground to the frame the stall begins to happen. Some rules would definitely have to be put in place ( a tuck HAS to happen during a stall or else the record is invalid, and all tricks must be stuck and not clutched) which should make it harder to spam records.

Longest hand spin, longest foot spin, longest planche, these are three other ideas for -30 records just waiting to be attempted.

As for the longest run that’s sad to see it go. The easiest way to add rules to that would be that each foot must cycle, hands cannot touch the ground, and jumping isn’t allowed
