Accidental platform tech??

[AssTAStic_ACA]

I did this mid tournament . At first i thought it was a fluke. Then it happened a couple more times in some other matches. After the down throw, i tried to follow up with a DJC U-Air. Though instead i got a JC grab and just went with it. My question is.

-is this actually a thing or a glitch
-Is there a way to practice this? if so how?
-How practical is this amongst various other options(i feel like this may be a super technical tech that may not be necessary)

Thank you.

Its not a glitch, its something that happens due to the fact Ness dips very slightly during the start of his DJ. If you double jump while Ness is basically inside the platform, you'll snap to it with 0 landlag. Its a 1 frame window as far as i know, but it is something you can easily practice.

As far as usefulness, if you can do it reliably, its around 10 frames faster than a waveland, so it'd give you much more time to act on things like tech chases.
