Cool. Can you repeat is consistently enough to use it to save your stats? I figured there was a jump out of the tunnel if Toni could jump far enough, but never tried a deliberate fall in that location. I have used that trick to pad my face plant distance records (299.19 using a different blue hell warp).
The best distance I could manage out of the unfinished tunnel is around 135 meters. I've since managed to beat that legitimately in a couple of locations (152.55 m). My best glitched distance jump is currently 423 meters. I'll bet there's more in the jump, I only tried it a few times. The same spot was used for the 299 meter face plant.
Someone reported another method out of the unfinished tunnel using a vehicle. I haven't tried it, but it had something to do with parking a car next to the blue wall blocking off the SSV tunnels, and running into the crack until Toni gets spat out the other side.
For a while I thought that all the tunnel warps wouldn't give much of an insane jump height stat, but then I noticed a warp on my video showing a height of 32 meters. This matches my best legitimate height record (32.36 m). I think I know a good spot for more height, but I stopped working on my glitch stats when the LCS record book came online.
