JOE stun combo

I can consistently land all of the hits up to the very last one that stuns…the jump D. Im about 60/40 with it landing. Can someone explain the timing to land that every time. Its seems like if i juggle them too high they lose their juggle state by the time the jump D would connect, and if you juggle too low they obviously just fall out of the combo.

what kind of visual cues are you guys using to judge when to use the qcb.p to launch the opponent and connect the j.D?

Don’t think, feel. Muscle memory, which comes from practice.
