the professor posted:

performance index = [(T-A)/T]*1000  
 where  
 T = total number of people in your races, including yourself  
 A = total number of people who finished ahead of you

like a batting average
so when is the performance index going to mean something
like to win the #1 plate you need a performance index minimum rating of (x) to be in the running

It makes sense now.  It just threw me that on the overall points, there are people above/below me whose PI varies greatly from mine.

But if they're only rated on 1 race, then it would make sense.

Are you wondering what it is, or why yours is so low?  :P  

Jack, you should come out next weekend and hang.
