Having a few tracking problems with my mouse @ 1800dpi, so I want to convert my settings to 450dpi to see if this fixes it.

Current settings - Abyssus @ 1800dpi/1000hz

sensitivity "0.8"
cl_mouseAccel "0.1"
cl_mouseAccelstyle "0"
cl_mouseSensCap "1.05"
cl_mouseAccelOffset "5"

Now since 450dpi is exactly quarter of 1800dpi, it's not rocket science to figure out the new sensitivity. 0.8 X 4 = sensitivity 3.2 and 1.05 X 4 = senscap 4.2, and using the "new accel = old accel x ((old_dpi/new_dpi)^2)" formula I get 1.6 as my new accel. So this gives me something like this

New settings - Abyssus @ 450dpi/1000hz

sensitivity "3.2"
cl_mouseAccel "1.6"
cl_mouseAccelstyle "0"
cl_mouseSensCap "4.2"
cl_mouseAccelOffset "5"

Now this feels about right, but the application of the accel still feels a little sluggish. Can someone tell me what my new cl_mouseacceloffset should be? Should I even be changing it or is it irrelevant when you change dpi and sens values? I've read a few guides on the offset command but it's still confusing me.
