Just sayin. You can't explain a matchup on paper and account for a players inability to always react correctly and guess perfectly. Diddy does so much damage from one connecting banana that the number of mix ups you have to win to maintain a lead (as well as basically not let Diddy get back to the ground) is huge when you actually factor in that Diddy can repel your pressure even without bananas.
The scenario you're describing requires marth to OUTPLAY the diddy kong player because it's read specific. He doesn't have "guaranteed" scenarios or particularly strong frametraps that allow him to stay in control like he does vs snake.
