Curious if it changes any strats or has any possible benefits in game when speed running.

Could someone explain or paste a link on this?

Things I can't seem consistent on: Quick duck after a successful punch Quick duck after a successful punch into another punch Quick ducking in general

Would like to know the detailed frame inputs required and the frame windows on each of these.

I'm running on Snes9x Retroarch for Android.

Not finding the info online so thought to ask here.

Cheers. :)
