worm is "regressing to the mean". It is a phenomenon that will occure with almost everyone who handicaps, because most of us really can't do this. It is also part of the reason that "touts" go south after turning pay. They have had a ton of success over a period of time, and decide to go pay right as the worm turns. (Bad pun, but hey......) I think the guys who suck at this for their first two years should go pay! They are about to turn the corner!
You will have the few who beat the "mean" over a long period, and those who will fall short all of their life.
Rocks is another prime example of the kind of guy who will mete out this principle. edludes fits the mold to a spot on match. There are several more out there, but what's wrong with being average?
Keep pluggin' guys!
