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?
