I agree that this approach doesn't really reflect gains that are being made by some of the clubs in our state. The weakness with this type of approach is that it shows "velocity" and not "acceleration".
For example, in the midstate, the merger of CSC/CFC has seemed to bring together a critical mass of coaching talent and players and from my perspective they are really accelerating. This is wonderful news in my book -- the midstate, and particularly the Columbia area, badly needs a club to step forward and increase the level of competition on a continuing (and not just one-off) basis.
Once you get past the intra-state competition, the sad fact is that SC is still ranked incredibly low (girls: 40 out of 50, source: gotSoccer.com). I'm hoping that we get a lot more acceleration from all of the clubs in the state so that we can really move up from the basement.
