For the elevation, where should the angle be measured?
- the vertical part of the arm that holds the LNBF behind the dish?
- the horizontal part of the arm that holds the LNBF in front of the dish?
- the tick mark on the bracket that holds the dish?
I'm using the tick mark (40 degree) on the bracket but when I measure the vertical part of the arm behind the dish it's about 10 degrees off (30 degrees).

There isn't any surface on the dish or arm that you can measure the angle with an inclinometer. Your best choice is what you did. THe Fortec 80cm has an offset angle of approximately 22.75, so the elevation measured from the vertical part of the arm behind the dish would be approximately this amount less, but this is a crude measurement, as it's dependent on where the mount is attached, ie it assumes that this section of the arm is perpindicular to the apparent aim of the dish, and I don't think this is generally the case, although it is often close.
Another issue is that the bracket with the scale may or may not be designed for your dish. My Fortec 90CM came with hardware in a box indicating it was for the 80CM dish, so no telling what hardware you got with your dish, maybe you got the 90CM stuff I should have received. :-)
But as mentioned by sagirma, expect the scale to be off by a few degrees. You can do what I did, in

to determine with mirrors how far off your scale is, but it's easier to just find the signal by trial and error, then note how far off the scale is.
