Fred,
20 arc min over 4 months seems like a lot to me. How many knob ticks does that equate to?
If I recall correctly, I got the results below 3 or 4 months after my initial PA.
************* AZIMUTH ************
MA: +183 seconds (+3.1 minutes).
Rotate axis East (counterclockwise).
For latitude -37.78°, the azimuth adjustment is 3.9 minutes.
Paramount: Loosen the East knob, and tighten the West knob 1.9 knob tics.
Sigma=16.578
************* ALTITUDE ************
ME: -147 seconds (-2.4 minutes).
The polar axis should be raised -147 seconds (-2.4 minutes).
Paramount: Raise the polar axis 1.2 knob tics.
Sigma=9.220
The soil under my pier is nothing special - mostly clay and topsoil.
I wonder if there could be something else going - there is a lot of maths and mechanics going on behind these numbers.
