Revisiting this because I got time to test it on 20xx on console.
So, I assume you mean to ask whether wd in place dtilt is more frame friendly than doing a regular run cancel dtilt?
if you are dashing and do both of those things on the earliest frames possible starting from the same frame of dash, then it's a little different
First, the earliest dtilt can come out is if you input it on or after frame 3 of squat, in which it comes out 1 frame later, which would be earliest 4 frames after inputting a crouch.
Run-Cancel on earliest frame:
Dash for 15 frames
Run starts frame 16
1 frame of RUNBRAKE
2 frames of SQUAT
input on frame 3 of SQUAT
Dtilt starts.
Total Frames: 20 frames
Dtilt comes out on frame: 21
I don't quite understand @
Yung Clap
saying that you input dtilt out of RUNBRAKE, which is why I went through all the states involved in the process. Don't mean to undermine what you did tho lol
Now assuming you begin your jump on frame 16 of dash (which is when run would normally start if you kept dashing)
Dash for 15 frames
Input a jump on frame 16 which starts KNEEBEND
4 frames of KNEEBEND or jumpsquat
JUMP starts on frame 5, and is the earliest you can input an airdodge
After Airdodge:
LANDINGFALLSPECIAL for 10 frames exactly
Assuming you are holding down to crouch through the previous state, you will enter squat the frame after
SQUAT for 2 frames
input the move on frame 3 like before
Dtilt starts.
Total Frames: 33
Dtilt comes out on frame: 34
So yeah, WD in place dtilt is actually going to hurt you by AT LEAST 13 frames.
If you wanted to break even, you could input the jump to start the wd on dash's frame 5, but by then, you haven't even covered much ground at all, which is very counterintuitive, and difficult to do lol.
So there. Disclaimer tho, I'm not a frame expert, but I just wanted to see if what I got matched up with Clap. I don't test much often, so this was fun lol.
