Notable matches:
Ryudo (G2) vs. Miakis (S5) - Not going to math it out, but I normally use a fairly generously low damage average for Grandia II due to their SP issues, and it might be enough to put Ryudo over the top.
Elhaym van Houten (XG) vs. Rikku (FFX) - Well, Al-Bhed Potions are legal! I think I could even be persuaded that all Mixes are legal as well (weird as it is that she can use items then she can't normally), which would make Rikku a pretty badass Middle - stall off Alchemist-backed healing until a broken Mix - but even with 50% Sleep Protection her stalling game is just lost here.
Wow... how did she beat Zelos again?
This was already covered, but figured I'd chip in anyway. That was a bit of a rob IMO, although she does have an argument. Weird, but guess it's a backlash against Tales hype earlier. Checking the Suiko 1 stat topic, Kasumi is 157% average speed... so if TB speed is taken totally literally and Zelos is perfectly average and Zelos doesn't OHKO, that is a an immediate 3:2 which is probably a kill. Problem with this is, while it's been a long time, I believe that there is a random element added to Suiko1 initiative - i.e. 120 speed does not always beat 119 speed - and a random element functionally moves everybody closer to average speed. I wouldn't be surprised if that alone was enough to put her at the <=150% TB Speed mark. Obviously there's also interpretations of TB speed that don't take it literally (caps, SDs, etc.), so that too.
