I apologize. I'm sure you're applying a high science. And measuring a hundred angles to the marks on an Invar leveling rod, many times, may show a pat...
A accurate anglular value is intentionally down graded by introducing an error? Unless the manufacturer stated that, proving that would be hard, a NIS...

Or in a trophy case next to your Curta and Berger.

Does anyone use 3 receivers with static observations anymore? And run networks of point-to-point baselines? And make a network of polygons of dX dY dZ...
A 20" second describes the least count on the plate. Not the angle it'll produce.And that determines the procedure that would be required to "better" ...
Older Ashtech receiver are plenty good for opus solutions. By today's standards, it's hard to make a 2+ static observation. But it works very well. 30...

That jet black in summer sun may be an issue. You might wrap it with a Mylar sheet. Like the gold wrap on used the legs of the lunar lander.
Accuracy improvement is a power curve. So to improve the accuracy by a factor of 2 (half) you wrap 4x, to cut that in half 16x wraps, another one half...
I meant inverse square law of errors.
No doubt. I just set my T3 on a bathroom scale - case and all. And then there is the battery box which I hang on the tripod leg.How much does that ad...
