Hard probably wasn't a good word. I'm sure it's overall easier than bouncing on him (the whole reason why I thought to try ground pounding was because I was too bad at getting the double bounce consistently). You just have to slightly time it because if you spam it, you'll hit him during his invincibility frames and fall off before getting the second one. With practice it should become pretty simple.
Not sure if you guys knew this (it's so minor that I didn't check), but you can crouch during Wario's landing pose after jumping off a rope to cancel the landing animation. You can use that during the second phase in Chortlebot to be able to react as soon as he falls.
