    this is a great site.. you can click between the past few years to see the changes..

    Looks like the street tire classes got hosed the most.

    slight increases in the stock classes and (~.04) and in ASP/BSP CSP seems to have gotten the largest "SP" increase.

    look at FS and GS.. huge bump. (maybe they should just re-class the mini and new cobra to where it belongs)

    OK, I geeked out...

    All of the stock classes have been trending up recently.

    Stock

    And Street Prepared...

    Steet Prepared

    And Prepared...

    Prepared

    Street Touring has a slight upward trend, but not like the others.

    Steet Touring / Modified

    And Modified (other than A-Mod, duh) has been slowing down.

    Modified

    Of course, all of this assumes that A-Mod has stayed the same speed, which may or may not be a safe assumption...

    I'm wondering if going to HPT for Nationals in 2006 (first year of the hard upward trend) is a factor. Less grip due to asphalt? I dunno.

    The PAX does not assume that that AM stays at the same speed. AM was getting faster until the past few years. Now. the BBR Shark had no real challengers and development in AM has essentially ceased. The graphs show most classes getting slower for a period of time before turning upward again. One major reason for this reversal is the recent rapid developments in R comps and street tires. The upward trend started in 2006 so it is based on 2005 results which was the last year at Forbes. But, most people are surprised to learn that Rick does NOT use the Nats in the computation of the PAX.

    The Nats Results for 2005 would have been really useless. There was the thunderstorm Tuesday morning followed by a major change to the north course because it broke up and then Stagnaro oiling down the north course. A CM oiled down the south course on Wednesday and there was more rain on Thursday.

    Wasn't the stock category realigned early in the decade. The graph seems to indicate that. The relatively flat curves for BM, CM and FM are due to the cars being GCR legal which limits how much they can be developed. I believe DM and EM have had weight added so that will slow them some. Also, in both Prepared and Modified, Hoosier has little competition so that slows tire development unlike in the other categories.

    Although Lynn's remarks with regard to the National event's influence on the new Index are basically correct, don't get the idea that the National Solo Event is ignored in the detrmination of the new factors. It is the only event where so much talent in ALL of the classes are shown, but it must be remembered, it is still just ONE event.
