Well technically if you get a game over you didnt do it right, so its not Die%

I timed it by doing a jump attack through the cryo wall into the void and the second i push the y button i stop it

I changed it to the "blue void" you have to fall in referring to the place you fall in the runs posted.

Endlessly fall in the blue void as fast as you can by any means necessary. We found it fastest to clip out of SOR and do the cryo BTB, clip into cryo, then clip out.
