Ok, I can't record, so I'll have to use words. If you start in training room, take a small step forward so Kano's foot is on the edge of the star, the tip of a D4 will catch a successful jumping 3. 10% damage, pretty useless.
However, a jumping 4 hits behind and can cross up on the way down if done two steps in, with the back of Kano's front foot touching the star. (Go too far and he'll turn around in the air. You don't want this to happen). As the dummy gets hit, you can D1-choke for 18%.
So, that's shit right? Well...
You can cross over tick. Block the kick, you're at -1 and can grab, and on hit... you can grab them out of the air too!
It's gets better though. 32 also hits, and now that we have a meter burn option there could be scope for a lot of damage. JI4-32-1+3 already does 23%.
I'll admit, you've got to be pretty spot on with the spacing, but it is a mix up. Maybe somebody can do more with this?
