But you can't do anything in between those dair hits, can you? I'm kind of confused why you mentioned it. I mean, couldn't you mix up your dair timings (like you do with nair) to make it less predictable? I'm just very confused.
I apologize, darling. I've been cruel to you for my personal amusement. I wanted to know how you would react to my comment (and to see if anyone else would believe me).
You are correct. You cannot action between the individual hits of Dair (outside of shield SDI) unless shenaniganry occurs (one or more of them miss because of height or whatever).
Anyway...
When I refer to the 'gaps' in space animal shield pressure, I am referring to the times where you are not shield-stun locked into helplessness. Usually their aerial-shine shield pressure works something like
Shine ---> stun ---> GAP ---> aerial ---> stun ---> GAP ---> Shine
However, this is not always the case as Fox (and Falco) can, on some aerial-shine chains, manipulate the gaps to create a really big one and a reall small one (or no small one, just a big one). Consult the shield pressure thread someone linked earlier (I think it's also in the OP of either this thread or my MU thread). In a general sense, the earlier your do your aerial after the shine, the bigger your 'gap' between aerial lag and the following shine will be. People delay their aerials to avoid this.
Fox's Dair
breaks this rule because the constant stream of weak hitboxes basically ensures that the end 'gap' will be the same size every time. Normally the point of 'delaying' your pressure on normal, single-hit moves (nair, etc) is to create a smaller 'gap' between the aerial's lag and the shine. But since dair is weak and has constant hitboxes, it doesn't behave this way.
So no, you don't really have to worry about 'delayed' Dairs. The timing to beat a delayed Dair is the same to beat an early Dair and so forth and so on. Because of the nature of the move.
That clear? If not, you're outta luck 'cuz I ain't explaining that again :x
