Interesting, I'm gonna have to test that some.
I did some testing myself, on the theory of backturn guard speed, and found some interesting things.
The usual AI settings...COM reaction = Guard All, stagger escape = fastest.
First things first...instant double palm (13+1 frames) will connect as a combo if you buffer perfectly. This will work whether in open or closed stance.
However, even if you don't buffer it perfectly (i.e. it doesn't register in the combo counter), there's a small window where instant double palm will still connect. This reaffirms my theory that you cannot backturn-guard instantly.
But why stop there? I need to know exactly how big this window is.
So through some testing, I found the slowest move I can connect (that doesn't count as a "combo") is another
, which is 18+1 frames (other things that also connect:
,
,
) . That is SLOW. However any 19+1 frame moves (such as
or
) will not connect period.
So, from this, my preliminary conclusion is that it takes 6 frames for the AI to turn around and guard (assuming AI is "free" to act on frame 15). It takes even longer for the AI to turn around and counterhold. This actually seems to be in line with what I expect. If I recall correctly, it also takes exactly 6 frames for a character to turn around and guard in VF5FS.
I need some help to verify this though. Currently I don't have anyone to play this thing with offline, so if any of you guys have a friend that you can test this with - see if they can escape any move faster than 18+1 frames. In the main time, I'll look for some other DOA character with a similar back turn attack and see if I get similar results from them.
Edit:
Just talked to Mr. Wah to see if he had any experiences with backturn speed, and he said this:
Bass' BT ground pick up throw is +11 frames. After picking the opponent off the ground, his
(16+1 frames) will not connect, which is 7 frames later, assuming the opponent is free to act on frame 11. However, a
is guaranteed, which is 14+1 frames, that puts it at 5 frames after the opponent can act. This seems to correspond with my findings. I'll keep an eye out on further data.
