For folks that run without in-game music on, here are some setups for dashing through the gate as it opens. The first is for a kill with VS and the second is with a nail (since this will affect nail cooldown). This takes some practice to get used to the freezeframes; using the WK flipping back animation gave me a better feel for it. For the second setup, I wouldn't recommend buffering a jump out of the dash since it can come up just a little short if timed perfectly.
Timing from the kill rather than the death animation is necessary to be fully consistent since, like Gruzmother, WK count as dead as soon as you land the final hit (which is what the gate timing is based on), but their death animation depends on how exactly they're killed (e.g. having to fall if killed midair, or not doing the flip back if the last hit is a pogo).
Saves somewhere between .14 and .24 to just walking through depending on how well it's greeded.
