The coverage of a lens ends where the resolution becomes unsatisfactory to you. Do you plan to use the films that you will make with this lens for enlargements or contact prints? If enlargements, how large? If you plan only contact prints, perhaps examining the ground glass, or carefully examining a projected image will work. But if you plan enlargements, I think you will need to make a film with the lens. Then make a print or examine the film with a loupe of a power similar to the maximum enlargement factor that you plan. You might find that the coverage is smaller for an enlargement because the outer portions of the image may have enough resolution for a contact print but might become too soft when enlarged.

Kelly, I had in mind a little drama that played out a while ago. In Act I, one landarc sold a 180/6.8 Dagor on eBay with the claim that he had personally used it and that it was very sharp and covered 8x10 with movements. In Act II, not long after, an individual using the name landarc (yes, the same) posted a long rant about the shortcomings of his 180/6.8 Dagor on the LF Forum (not here, Q. T. Luong's). It wasn't sharp at all and it didn't cover 8x10. How's that for balls?

You should also do your test with a distant scene because the coverage expands for close objects -- as you focus closer, you move the lens farther from the film, and the same angle of coverage corresponds to a large diameter of coverage.
