Sean,
It appears to be working, but permit me to make one suggestion: You show the initial GC course, but you do not show the rhumb line course between the Departure point and Waypoint 1, which I believe should be 245.7º. Perhaps adding "Waypoint 0" to the list would be something to consider, with the course and full distance listed. (I had a problem with the fact that you are using the GC total distance, which would not be the same as the total rhumb line distance, but it is covered by "Approx.".)
Though it has no real value, you might also consider putting the Arrival coordinates at the bottom of the list, with the course left blank and the distance shown as 0.
Stan

Stan et al.,
I believe I may have fixed my spreadsheet. Have a look at the attached and let me know if you discover any errors. (Again, the spreadsheet is protected, but with no password.) Thanks!
Regards,
Sean C.
