Definitely pepper at least one line in 50 ft sta for 300 ft for calibrating chains. I think a braced quadrilateral. Observe all angles for a very tigh...
Just use radians. Formatting isn't an issue. And formulae are easier to write and trouble shoot. But I didn't think a single cell dms was even possibl...

Found it ....Page 9, near the bottom. Center weighted grid factor, for proper grid factor of long lines. Might make up for your difference.
