I've been having issues connecting the aerial combo after 4D~A 4D~D. Is there a certain delay that I should have in mind? I have pulled it off maybe four times, never consistent. Kind of weird to me I guess, I'm used to CT Jin's almost automatic aerial combos.

I'm having issues with the midscreen 5A > 5B > 2B > 623B > d. 5B etc... on jin Jin techs out of 623b before I can reach, am I just struggling with the timing of the dash after the 623B??
