More Star*net interpretation
Slugging my way through finding “Elevation differences” (primarily due to botched measure ups in SurvCE). Star*net shows this:
I see there’s a problem with station 900. But if the StdRes’s are so high, why is 900-800 the same as what I measured from 800-900 (28.9361)?
If I messed up a prism height at one setup to another but not the other to the one, wouldn’t these be different? -

I don’t understand the reference to “what I measured” because there is no display of your measurement values. The values you posted are the elevation differences between the adjusted coordinates of those points. So every occurrence will result in the same adjusted difference displayed.
I see one 800-900 and two 900-800 measurements represented The two 900-800 must have had exactly the same measurement numbers in order to get the same residual. No? That residual is different from the 800-900 residual because other measurements (700-800, 600-900 etc) pulled the best fit coordinates a different amount from the 800-900 versus 900-800 measurements.
What was the question … ?

Oops. You’re right. My bad. I posted the adjusted coordinates.They would be identical, wouldn’t they? I looked at the originals; then went back to the field book and found an HI that was not entered in the data collector. Once I changed that, the residuals all dropped like a rock. I’ve got to develop a better procedure for making sure that every HI and HR is entered in the DC.
