When folks talk about "dilution" being a problem; here's what my translation typically is -- "Some parents/kids are stupid for not being a part of my club, therefore I'd like to shut down their club, eliminate their choice, and thus force them to help my kid at my club."
I've said for a long time that "dilution" is only a symptom; the root cause is a lack of differentiation of services and a lack of penetrating underserved markets. It's been a long time since I rigorously did a club density exercise; but here's a rough "dilution" view -- from it I would guess that the weakest clubs are in the upstate.
