You are not "fine tuning" the sat. You are attempting to compensate for a misadjusted dish. I am in southern Indiana and with only a 76cm dish I am getting with even consistancy everything from 30 out to 123. The dish could move farther west but hits a physical obstruction (house).
If you are getting G10R with USALS reset the sat with USALS. Now with it pointed at G10R slightly push up and pull down on the dish watching signal variation. Now run out to the farthest east sat you can see and do the same. Did they behave oppositely? If so you are not correctly lined up on true south. Start by rotating the assembly slightly on the mast towards the direction where up made signal stronger.
Continue this exercise until you get a drop in signal regardless of pushing up or pulling down. Now you have south lined up. Now it is only a matter of figuring out declination and elevation. In simplistic terms, declination widens and narrows the arc. Less declination (dish elevation) the wider the arc. Elevation (motor elevation) positions your arc in the sky up or down.
Given that move to your true south sat and using elevation adjust for peak signal. Now start "walking" around the arc noting what you have. You are creating a map of your arc. Any adjustments made from this point are double adjustments. So if you lower declination by 1 degree you will raise elevation by 1 degree. This manuever would make your arc wider and align you again for peak on center.
Work with this as your time and patience permits and you will see more channels and clearer picture. You will also hit all your sats using USALS
