Maybe this will save 1 or 2 seconds since you won't have to wait for the barrel to roll by

Small update. I did some testing with this glitch and don't think it's worth to go for in a run. -It doesn't save a lot/no time -It's a high risk because the jump is very hard and if u miss it. It's basically an automatic reset. I'll be looking for some more glitches and make a forum post when i find something.

This doesnt look too good

no time save in a run
