5. Summary

Of the three methods demonstrated here, the Compass Rule is the most commonly used for simple traverse adjustments. While the Crandall Method is a quasi-least squares approach, it's up to the user to decide how to deal with random angle errors. When traverses become more complex with cross-links, a true least squares adjustment is the best. See the XV. Least Squares Lite topic.

Traverse Adjustment is an Excel workbook which performs Compass, Transit, and Crandall Method adjustments on a loop traverse. It uses Visual Basic for Applications so be sure to have macros enabled.
