That's the thing: In my mod, you don't have to jump perfectly. Let's say you jump two frames later than you're supposed to while having the knife equipped. In my mod's default settings, you would have (perfectjumpspeed - 250) * 0,975^2 up/s after the jump --> ~95% of the speed of a perfect hop.
As you say, with your cvars it's still not possible to bhop consistently like in HL1. With the mod it is!
