You agree, good.
This may have been lost in translation but...
The matchup chart is meant to provide insight on how well characters toolboxes butt heads with other character's, to my knowledge. Same toolbox, same odds. Any speculation or metagame theory beyond that is irrelevant and should be redirected.
I would associate "most optimal way to win" with "perfect play" in this case. Thus, you're agreeing with the statement you're attempting to discredit.
