I know there are already tons of di threads out there, but I've read many of them and still don't quite understand quarter circle di. I've heard that using quarter circles are easier to do and more optimal than tapping or smashing your control stick for sdi, but can someone explain why? and also how and when to use this di? like for example, if i get hit by a fox upsmash or a forward smash or a drill, should i use this di? what inputs would i do to execute good quarter circle di for each situation? thank you very much.
