that is all you need to know really
But, allow me to elaborate. I can only apologize if i manage to offend you, it's not meant as an attack at your person.
A: The application is meant to make us able to judge YOUR skill, and that's really fucking hard when it's not your opener being used. I don't think that requires further explanation.
B: In your splitcap replay, pausing and E'ing it one frame before impact and then resuming results in a singular split. Since the DMs in your replay occurs at the exact same frame, pausing and resuming it like that should produce the same results. Since they don't, it's fair to assume that either a glitch happened, or you went into the replays file to add a few dismemberments. Neither are acceptable, but glitching is at least not intentional.
C: At the risk of sounding like an ass, your moves aren't impressive enough. Needs more smoothness, more style and what not. I'm sorry to be so blunt, but you just need to practice more. Move more joints at once, move them more frequently, and apply relaxed joints as well. I know they're harder to predict, but it's actually much easier to make relaxed moves look good than it is to make hold-all moves look good. And even then, doing the latter will very likely require relaxed joints, so yeah.
