What's that gemma?
What constitutes a bad starting frame? The table you listed seems to suggest there's three sets of 5 frames which are acceptable, though the first one can potentially be lost due to frame rules. Are you saying that there's a frame where if you release the weapon attack on that frame, the first three sets of 5-frames of the attack are all lost, and the Girl crouches first, without performing the charge-forward animation at all? This is a phenomenon I have never observed.
I've been trying to reproduce a failure, and after ~50 successes I've given up. The odds of me failing to observe something that should happen 20% of the time after 50 tries is 1/35000. And this isn't the first time I've tried and failed to reproduce that problem, either. I have to conclude you're doing something wrong, rather than getting screwed by frame rules.
This trick is not hard. In that video, you're acting as though it is hard by putting the girl close to the spring. Place her a tile and a half lower than that and, according to your own table above and consistent with my experiments, you have a 10-15 frame window to press Y after releasing B.
