I know that I'm late to the game but I am thoroughly confused. I got most of the way through training 3 & hit the "Recover" tutorial. I just don't get it. Are you supposed to button mash all 4 buttons at the same time repeatedly, rapidly tap one of the buttons or tap all four in a circular pattern? I've tried all of these and get nowhere.

Also, do you tend to hold your controller in a standard fashion and tap the buttons w/ your right thumb or do you use a non-traditional grip so that you can tap the buttons with your fingers more like a fight stick?

Thanks!
