I definitely agree with he inverse law, at least in my experience. Lots of rehearsing starts to cut into your bottom line, too, if the players don't all live in the same town.
I don't mind rehearsing. However, I feel the rehearsal should be used to actually work on material that would benefit from rehearsing. If you're covering Song for America by Kansas or some Eagles's songs with difficult hamonies or writing original material, then a rehearsal will be beneficial. Don't waste my time, though, to rehearse because you want to run Johnny B. Goode, I Wanna Be Sedated, or Roadhouse Blues. Competent musicians should be able to do their homework on that type of material and put it together on stage without an ensemble rehearsal. If not, then they need to hit the woodshed.
