I'll throw this in too. Being a newbie with no dish aiming experience and a dish with no scale, I learned the hard way...
Elevation angle for 125W from
dishpointer.com indicated 36.9° elevation. I tried for an extraordinary amount of time around at 36.9° to find a signal. I then found out about offset angles. The Patriot that I have is supposed to have a 27.7° offset angle. I subtracted the 27.7° dish offset from the 36.9° total angle and came up with 9.2° for the dish angle. With that knowledge, it didn't take too long for me to get my first lock... What a surprise and relief.
Anyhow, this is how I used the angle indicator on my particular dish. I believe you have a Channel Master (?), so it will differ.
This is a closeup of the angle indicator with the dish recently peaked (i.e., yesterday) for 125W. In my case, the angle indicator is a few degrees past the 9.2° calculated for my position.

Spongella, maybe this will help you some or at least give others some reference.
EDIT: I used the same angle indicator to ensure the pole was plumb (i.e., 90° N-S and E-W).
