I'm trying to get the number of units it takes to reach a velocity of 1300 starting from 0, going straight down, and with normal gravity (800). According to the Wiki, velocity is the number of units that a player tries to move per second, but it takes ~1.44 seconds in my test measurements to reach this velocity. That said, is there a way to use this info to get a unit measurement?

velocity (v) = acceleration (a) * time (t)
t = v / a = 1300 / 800 = 1.625 seconds to reach your desired velocity (if you start from a stand-still)

distance = (a*t^2)/2 = (800*1.625^2)/2 = 1056.25 hammer units to reach a speed of 1300 units/second.

I don't know how things like sv_airaccelerate affects this but that is a basic calculation of the speed and distance.

Thanks for the info (and for how you calculated it).
