How does the speedboost work in world 5 in BBF's wr? Timestamp included :

I'd like to know frame windows/just in detail stuff about how the trick works if possible ^^

You hold down shoot (and down, which is the same as shoot because double shot) and jump through the platform at a certain angle. It's very inconsistent.

Oh, the one after the Wario chase is very consistent and easy to do. The one before Wario Chase is very random to get.
