I've watched the WR for Jill Major Glitches and tried following it exactly, but the Plant 42 skip seems extremely difficult to replicate. Is there a sure-fire way to get the glitch? Or is it genuinely just really hard to get right?

So when I get bit by a zombie, whether it be the intentional bite you take or any accidental bites along the way, I always take 3 munches. However, the faster runners seem to only take 2.

I've been told by one person that you mash action, told by another that you mash left and right, and told by a third that you mash all buttons to get zombies off you faster. Nothing seems to work for me though, I always get stuck taking 3 munches.

Is there any definitive way to guarantee only 2 munches from a zombie?
