Based on LeDude's posting decline (and the apparent reason for eliminating all decent posters from competition) I could draw some astonishing correlations. Chico would have to provide the hard data, however, at face value I see these conclusions.
1. There is a strong inverse relationship between coaching experience and posting ability. I would not be surprised at an r value lower than -0.8.
2. I was tempted to say the same inverse relationship exists between education and posting ability as Ledude's advancement in college seems to indicate. However, that would lead to the conclusion that high schoolers have the best posting ability. Since this is clearly not the case, there must be some curve or cyclical relationship. High schoolers have low posting ability, early college students seem to reach a relative maximum, late college drops down. Perhaps post graduate rises some and parents of young children. Once the children start playing soccer, the parental posting ability drops dramatically, and then some of the old people with nothing left in their lives but the message board often show some sparks of wisdom and wit (though tainted with pessimism and grouchiness--the "dark side" of posting). The function relating posting ability to education/age is a complicated one.
