So, I'm thinking t achieve this, divide 120/1.25 and that = 96.

Set cg_fov at 96 and cg_fov scale at 1.25. This will result in a 120 hip fov and 90 ads fov.

Did I do this correctly?

If I wanted to make my hip fov 120, and ads fov 90, how would I achieve this? From my understanding, cg_fov adjusts only the hip and leaves the ads at default (65), and cg_fovscale adjusts both equally. But how do I adjust the two separately?
