This looks potentially very useful, but I have not yet explored defining sd settings in my survey data. So I may need to learn a bit more in order to use it. I spotted one potential error? In the grade 6 section, the compass bearing is to 0.125 degrees. But the clino is stated as 1.125 degrees. I think both should be 0.125 right?

Hello,
for a recent project i made a grades file (based on the BCRE-example in therion distribution) for UISv1 specifications (see attachment). It would be a pleasure for me if it is useful to somebody; it would also be very nice if i could get some feedback on it.
With the naming i had the intention that exporting from databases is easily doable. The prefix is "UISv1_" followed by the actual grades number. I included all the grades to faciliate documentation inside the th-files, so one can stright export "-1" surveys too.
With best regards, Benedikt Hallinger
