i have a punch that uses the push pull principle also. my opener has a less drastic leg raise or non at all so i also push off with the leg. i don't think my variation is as fast. Perhaps thats connected to the single leg stance of yours? granted i havn't checked out all the replays yet. just the gif, animation thingy.

that bifurcating one was awesome. the replays i have of us have a few of these punches i think. no dms though. maybe one frac. can the punch be held for another turn or will the positions change too much?
what type of attack were the other guys throwing that got the best result? mostly youtube snapkicks?
does the wrist need to be contracted for power?
does a grab hand result in more dms? years ago monkeyapex showed me that a second turn punch is more likely to dm with a grab hand. im not sure if it was specific to his punch or in general. i suspect the grab hand kind of turns it into a ripping motion.
what are your preferred follow ups?
do you ever get your arm stuck/trapped across your body after the punch?
how much range control do you need? it looked like some of the messier ones were close range punches.
