Ah okay, I must've been mistaken. I thought that he was saying it was start-up/block advantage/hit advantage. That's why I thought he was saying that if your opponent gets hit by a f4 or a f3 you would be at enough advantage to guarantee an OH/low mix-up, in the same way that connecting with Kitana's cutter or Ermac's 321 in mk9 gave you enough advantage for a safe jump.The numbers are spaced as if he was saying startup/BlockAdv/Recovery. Or at least that's how I read it. Meaning after a blocked f4 the advantage would be 0. So the OH/Low options are only slightly negative on block, but their startup is 15frames and 16frames. After a blocked F4 they both can be beaten by a faster normal like a 9frame combo starting string or interrupted by an armored special... Not good.
Seems like it would be more gimmicky than a real strategy to mix people up. Like Qwark said after a blocked jump in you're + enough for an unreactable 50/50, but after a F3 or F4 you'll get blown up.
Unless there are other unique strings that follow up after a F4 or F3 not listed it'll get blown up every time.
My bad.
