Okay now the air physics should at least match up.
Physics tick rate went from 100 to 200 to assist bhop acceleration, air acceleration values match up (sv_airaccelerate = "10", sv_accelerate = "10" [that is ground]), ground friction should be close enough. Unfortunately the circle jumping isn't as effective right now but I'm struggling to get accurate values that represent ns1 so the current issue is that I have a choice between having the player take a long time to slow down, or not be able to wall strafe accurately. Inserting the true value of "4" as friction makes the place all slippery, it really isn't as simple as copy and pasting.

This is on my TODO list. As well as getting jetpacks to function similarly, though I do not have effective experience and don't know the values so jetpacks won't come anytime soon.
