Are you using mouse acceleration settings in Reflex or QL and want to get the same feeling in the other game or driver? Do you want to take your driver settings and use them in a game where the computer doesn't have the driver installed? I can help (if QL is involved, I'm assuming cl_mouseaccelstyle 1). First, here's a table of the equivalent options/commands between the driver, Quake Live, and Reflex:
Use this calculator if you want to convert from Quake Live to Reflex or the driver:
Note: Once you've set post-scale values to work as m_yaw and m_pitch values, you will want to set m_yaw back to 0.022 and m_pitch back to 0.022 or -0.022 (depending on if you use inverted mouse).

Use this calculator if you want to convert your driver settings to a specific game:
There are multiple ways to perform these conversions. If you want to do any math yourself, keep in mind that sensitivity is multiplied in before the acceleration, offset, and sensitivity cap calculations are performed, whereas post-scale values are multiplied in after.
