- 4-2: 3 frames saved by improving subposes for the route and final birdy.
There's a few limitations for the final bird.
- His Y position. Since the bird follow's Ryu's Y position, we need to sacrifice that 1.5px to touch the sticky ledge to raise his target Y pos (ourselves).
- For same reason, Ryu needs to jump down from that upper platform too let the bird fly high.
- To combine these, bird should be manipulated to hit us at desired Y position (which would be 128 peak jump) by manipulating his X position which either ruins the "upper platform route" or takes too much time to engage us.
Other note is that sacrificing X position is fine, since boosting for 9-10 or 13-14 frames is 4.5-5.0px or 6.5-7.0px X travelling, surely enough to catch the ladder. So now going to reoptimize it with these in mind.
