Note, if all you want the lens for is shooting resolution charts, then go hard, and your 100 lp/mm number is probably as good a guess as any, and film is not the limiting factor, as Tech Pan will resolve over 200lp/mm at 1000:1.
If you want to know what the lens will really do in a pictorial situation, toss the USAF chart, it's isn't worth the paper it's printed on.
The best resolution test I have found is distant tree branches against the sky on a still day.

And examine the negative with a loupe... (A great way to get dissatisfied with your lab's printing work!)
In a use-what-you-have mode, being a city dweller, I shoot a lot of distant telephone and power cables against the sky.
at least with your method, when you're done, you still have some scenery with trees.
