so if you use a hovered aerial and an aerial, they will be performed for the same frames. If you hover cancel an aerial, it will require less frames. But you must touch the ground to get the hover cancel? You can't be juggling an opponent, chasing them into the sky and hover cancelling aerials as you go? I don't see any practicality unless you are on the ground or near it? Although I suppose you can be falling toward your opponent, throw out a hover just above the ground, use an aerial and cancel it, yes?
Also, i just want to be extra clear, do you have to move mewtwo during the float, after inputting the aerial towards the ground? or is it the cancelling of the float with the aerial that returns mewtwo to the ground? I suppose I can just go TO THE LAB!
EDIT: So Im back from the labs, and Im looking for a little input (pun most definitely intended). When I go to perform hover cancels, I tap jump, then immediately after input down on control stick to initiate hover. When the frames are good, I input F-air (c-stick), and keep holding down until i drift into the stage. Rinse and Repeat. Im semi-effective at it and was wondering how others are doing this with their inputs.
Also, when is this especially applicable? Opponent jumps in, aerial lands on shield, you hover cancel fairs out and counter pressure / combo? Do you want to try to string fairs together or does it make more sense to put out one fair, double jab then dash and immediately JC a grab?
