We all just got back from SoCal and saw how they run. Very different philosophy with cone usage and transitions. The courses may have been larger but the flow into the elements was smooth and wide lanes to choose a line.
Took a while, here’s ours…

Diane: http://www.youtube.com/watch?v=OewJyIu0hnwFully prepped cars make the best data points because the PAX number is fully exploited. You then have to add up the points…
We made two changes after the BMWCCA event and Praneil feels that after Oakland’s SCCA event we have her dialed in but the adjusted times are skewed dramatically.
Maybe…
Your car is more like an under prepared STU class car at .846. To be competitive in class you need the engine mods and lightening. Light exhaust, headers, a tune, light weight seats.
You were 5.993% slower than Justin using the STX to STU PAX adjustments. Your 50.276 raw time adjusts to a 48.770 in the BMWCCA system but to equal SCCA it should have been a 49.398 or 88 points instead of 80 points.
Your example is tough because the car is not prepped to the highest levels within the SCCA class.
SCCA has thousands of samples throughout the year from all classes. Every year the class pAX value is changed based on the last years outcome. At the National level the top 100 cars might be separated by an adjusted .5 seconds. Their goal is to handicap the entire field for the same adjusted time. AAS and UFO use the same PAX system as well. I calculate based on Praneil and Justin’s times our BSP car should have 97 points instead of 106. That would give the win to Justin by the same percentage as the SCCA index.
These are two very prepared cars for BSP (mine) and STX (Justin/Mack)
SCCA Index (PAX)
BSP .858
STX .827When you compare the adjustments they should be pretty close but they’re not…

Thanks but Praneil beat us all. Two more changes to make and Olivia should be done. SCCA Nationals here we come.
Here is the original split video of Praneil and me with grip and speed data…That’s a lot of information to process for me. I think the video alone is adequate.
GGR does a three run group system: Red, Blue and Green. They rotate through twice and do 10+ runs everytime. NO lunch and hot cutovers.
