Been testing some more, this time against goro's command grab on reversal. Although these strings (such as b121, 21, 121 and s1) are listed as +2 and the grab is 8 frames, the best you can do is get it to trade with his 9 frame b1 followup. For some reason this also happened with lackey's roll even though it's one frame slower. I think either his b1 is really 10 frames, his strings are only +1, or something is really up with reversals. The thing about b12u2 is strange too. Yeah it's definitely neutral since I can only get command grabs to trade with really tight execution, but why would they list it wrong?
I just was in the lab for 15 minutes testing with Mileena's ball roll that is eight frames and low profiles Goro's pokes. The results are weird. 2,1 I was able to many times stuff her roll out completely despite it low profiling pokes with down 3, but then there were several instances where she was able to trade or sometimes beat it. Reversals if I recall come out a frame faster than if you were to try to get out with a normal. The blockstun in this game is also all over the place. Like I said, the way reversals function in this game is weird and while the A.I. is capable of just performing the action without doing all the inputs and reacting that a human does, we still have to manually do them and react to the frame traps.
1 or 2 frames goes by very quickly. I am assuming that's the cause for inconsistent results. Even if you're plus 12, if you hesitate or are late your opponent may still be able to escape your pressure and punish you.
I've used all these strings offline against opponents at tournaments though and the frames are reliable for sustaining pressure, but even if they were all neutral or only plus 1 since Goro has 6 frame low pokes he'd still be likely to win post blocked anyway in most scenarios so it really isn't game changing either way.
Edit: I also tested this with Kitana's 2,1 string and got similar results to what I got when I did Goro's 2,1 string. Mostly stopped her from rolling, but there were still several instances of trading or beating it out, which I will attribute to human timing as well most likely. May have video in a couple hours to showcase this.
@dennycascade Just to show you what I mean. 2,1 is plus two on block for both Goro and Kitana, but watch these:
