Actual Dish Elevation with HH100

Hi,

Let's say that I completed all the rotor + dish instructions as illustrated in:

http://www.sadoun.com/Sat/Installati...stallation.htm

What should be the actual measured elevation angle of the installed dish while it's still zeroed out on true south?

My lat. is 37.13N and long. is 80.42W. So I set rotor elevation to 37.13 and the dish elevation to 24.1. When I measure the true elevation angle of the dish with this setting while it's still pointing on true south, I get a reading of about 38 degrees using Johnson angle reader. While, AMC 5, which is almost located at my true south (off by 1.6 deg.), requires a dish elevation of 46 deg. as per the elevation and azmuth calculator in:

So, there is about 8 degrees difference between where my dish should be pointing and where it is actually pointing as a result of the installation. Since I checked all the numbers so many times, and checked my installation against the manual and instructions online, and they all look in order, then I can only guess that there is either an error in dish elevation calculation for HH100 or an error in the elevation calculation for AMC 5 for my location. The best way to find where the error might be is to figure out what the actual elevation angle of the dish should be while pointing at true south. Anyone knows how to calculate it? Note that the calculator in:

Will not give you the actual angle that you can measure with the angle finder. It will only give you the angle in reference to the rotor's journal, which also have unknown elevation itself.
