in theory yes…but practice wise you actually see there very good what happens when you do it alone.
just checked his mid screen starters ssj goku combo where he manage to get. 3720.
with some changes and for sure still not optimal i get 3745 in trainingsmode with a jump in heavy as a starter as he did in the video.
with a low medium as a starter even more.
collecting the really optimal stuff will just work as a team. just grabbing some vids from the web is helpfull too (see my dojo)
but thats not neccessary the optimal damage output you can get in these videos.
