Dunno if this is old tech or not. I know Rojikku found a cool teleport home combo for Hayate, but I'm gonna leave this here in case if it hasn't been found yet. Thoughts?
14~25 of charge frames. Counter Hit multiplier. ~ means cancellable range, cancelling right after the 14th frame is the easiest and most common timing 7 of teleport "startup". Counter Hit multiplier. This is the only part that is shown in the Move Details list. 33 of teleport recovery. Normal Hit multiplier. The actual teleport occurs on the 1st frame of this animation. TL;DR-but-inaccurate-version: Hayate's teleport is 21(1)32
