Why is any performance index needed? Why not use a straight points awarding system like most orgs do?
Pretty simple system and it works well.
as Mike stated, it was an attempt to keep someone from just getting a #1 plate or class championship by just "attending" and finishing, even if nowhere near the front.
I agree Mike, it hasn't exactly had the desired affect but was an attempt at least. A BIGGER problem in my opinion is the end of the season double point round. Racing all year could have lead to one or 2 riders being very close (but they only do a few events per weekend) only to have someone decide to show up and run every race possible..Or, one of the riders sneak in an extra race. I don't see that as much pf a difference from the original point system when there was no PI calculations to adjust total points. A slow rider finishing in the back has no chance with the PI in place (as a performance index of 200 will not get you a championship) but those are typically not the riders chasing championships . Anything can happen, and there is NO PERFECT method (except for one that has me winning a #1 plate..LOL!)
I have had discussions with some pretty smart people that have "been around" and a couple ideas may even things out.. 1) no double points at final round 2) limit the number of classes that can count for the overall championship. 3) perhaps be able to throw out the performance index in 1 class allowing a rider to race an event at a favorite track that he normally would not enter.
ANOTHER idea, would possibly be not allow points to count toward the overall championship of classes you did not run at say, 80% of the years events.. In other words, you can't borrow a wee bike to gather up double points when you raced 600's all year.
Riders should be rewarded for making every round even if they are not front runners, that is how it is in ANY series of racing be it AMA, MOtoGP, WSB, etc. Riders should have a chance to go head to head, and if one crashes or has DNF'S or can't make rounds, they can't win class championships. Consitancy and making the commitment to attend a SERIES (not a few rounds) is part of securing a class championship or two (or 29).. If a rider wins a championship, no matter if they won a race at all they should be PROUD, not ashamed.. i
