Simple to test Cliff

It is simple enough to test to derive the standard error of a direction angle taken as the mean of both faces. In your situation, A standard error of +/-1.0" for directions taken (mean of F Lt and F Rt) with the lesser quality Wild T-2 means that you'd expect the angles to have standard errors of about +/-1.4" unless the Wild instruments are much worse than the Zeiss one-second theodolites.

What does analysis of variance in your observations give you for a standard error?
