Lao hat spin combo

[UMK 16 Bit]

I'm trying to master the hat spin juice where the dive kick whiffs. If the spin makes them fly way up in the air above the screen I can hit it but if they don't either the dive kick hits after the JP or I'm too slow and it doesn't come out at all. So is my problem I'm doing something wrong or is it impossible to hit sometimes? basically what I mean is if they jump straight into it I can get it everytime but a hit like raiden teleporting into it it never seems to work.

I've only gotten the grounded spin to jp->whiff dive kick on female ninjas and even then you have to slightly delay the dive kick for it to miss. For some reason their falling hitbox is higher than everyone elses.
