The guys that like to race around the cones will come back, no matter how bad they do*.
The guys that are not happy with less then consistent top finish will not.As wound up as some people get up about PAX(It must be in the Bible somewhere?) it is just for fun in the end. So race, check your results, freak out, then really freak out when you PAX

then have a tasty burger and go home and have a beer. Think about what you can do to improve next time, play some GT4, or some GTA. Have a beer. In the end you got to drive your car to a limit that would get you in deep trouble with the BLUE under other circumstances. It is Good Times.
* I have a customer that races cyclocross, he gets lapped(yes, LAPPED) every event, but he loves racing and goes the whole season. He loves to race. The finish does not matter(to much) to him. Nor should it be the beallendall for any one doing this kind of racing.
