(I made a topic like this not too long ago and was just going to dig that up but then I read the rules like a good boy) 
After playing with Nero for a while now I have made it second nature to try and maximise the damage done with Buster moves by repeatedly tapping it to get that extra slam or swing out of a move. I also have made a habbit of repeadedly pressing the shoot button during DT buster moves to add a few swords to it.
I still don't know if tapping the Buster while fighing bosses helps increase the damage done by these moves (even though I do it anyway) but today I saw a video of someone fighting Echidna as Nero and noticed that they were actually throttling the exceed button while Nero had his sword in her and it seemed to be doing a hell of a lot more damage. I always noticed the little bar you get but it never occured to me to try and rev it while stabbing her.
Does anybody actually know the ins and outs of how to maximise those moves? and does tapping Buster while fighting bosses really make any difference?
