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.

how does the gradius speedboost work?
