I've found a way to pressure that apparently reaching a max of -999999616.00. It's useless due to the fact that you can't utilize it, but I thought I'd just mention it, wanting to seeing if anyone else has found this as well.

I know, but with the way its done, the game DOESN'T RESET it back to -256 or 256, matter of fact, the pressure with stay at that level on ANY AND ALL Air Settings, until you remove the SING from the screen.

@ Billion57 Yes I did. But it doesn't matter because you can produce pressure just like this with THDR, just not near instantly and without it staying, due to thdr constantly exploding when it touches the GPMP that's pulling it together. @ boxmein No, the game was unpaused and the pressure remained at 999999616.00. I did note that setting it to different air settings and pressing "I" to invert the pressure with the game UNPAUSED, made a shell of SING shoot outwards. The pressure remained the same until I did it enough times to make the sing go away, thus ending the pressure spikes.
