Chipp having low defense isn't any specific advantage for Dizzy in that he has to worry about getting put into an ambulance after 2 hits against anyone. How could one think this isn't such a bad matchup for Dizzy, I mean just look at Chipp:
Triple jump = zomg you're never getting near him and most of Dizzy's normals are very situational not the best for catching him in the air, where he will be. In the air his dust beats everything. There's 2S for anti-air, but when you eat enough of his j.D that doesn't seem fun anymore.
Teleport and fastest run speed = zomg you're never gonna summon anything, Dizzy is so good without summons.
Yeah he does crap damage, but he's gonna hit you 20 or 30 times while you're sitting there doing nothing and Dizzy is in the running for worst in the game at getting out of pressure. Yes you'll do insane damage if you manage to hit him, but its mad risky for Dizzy, almost to the point of not being worth it, which sucks because you have to hit him to win. Definitely her worst matchup.
Against Jam just watch that tension if you don't wanna get wasted by FB Puffball, since that's usually how they happen. Feet on fire beats anything you have including 2S, but if she's doing it enough that you can react to it, just block and punish. Whats annoying about Jam is that she has more pluses on block than Lane Bryant, which means tick throws and the fact that all of her normals beat yours. But at least she isn't bouncing around 6 feet above you or teleporting over your head from 20 feet away. Much better chance at hitting her with 2K which is Dizzy's strongest option for knock down alongside throw.
