I have tried it here in PA. and in Va., and if everyone stops being stubborn it can work.
FYI, I run the South Fork Peeking Groundhog Match.
Check out the website for attendance and my attempts at making a schedule "shooter-friendly" and not to simply suit our range rental. Yes, it made more work but I was willing to try it.

The key word is "compromise". No one completely wins in a compromise.
Of course, it won't be perfect. However, even if each area club compromises just ONE date during the entire season, then the limited number of local competitors win via more matches and the clubs win via increased attendance. Where is it written that matches have to be exactly the second Sunday of each month? What is wrong with a Saturday, etc., etc.? I am sure you get the point.
Look, it is your match and you run it how you see fit. I have shot your match many times, and enjoy it. I remember years ago when there were 100+ shooters at St Thomas. However, I am not going to shoot St Thomas if there is a similar match closer to me on the SAME date. I think I speak for a lot of the LIMITED number of competitors in the area. Your 15 "loyal" shooters would have some company.
