I've TAS'd 8-3 to within one frame of hitting the top of the flagpole with a 244. If it's even possible to save that last frame, would it be enough to save a framerule over a 242 FPG?

They're the same framerule.

ye 244 is posible at perfect frame for TAS only, but it even lose 2 frames over TAS fpg 242, anyways getting the same framerule than it cause you have to slow a bit, 244 is not posible with fpg so you cant save it, you would need to be at least like 6 frames faster so you could do fpg in 244 and definitely save it

You need l+r to get 244 on the timer when you grab the flagpole without doing fpg.
