You won't have accurate data from any run sheets. It all depends on the driver, and the statistics on median MPH in the class.

I would bet the median MPH now for SST is 140+. Thus your data will be skewed because there are less low MPH cars in the class, thus less winners.

I won the division 4 title going on average 118-123mph in 2011. I go on average 128-132 now. I drive better being chased than chasing because that is what I am used too. To me its not easier to judge chasing someone, it's easier to see, but calculating the closing distance is easier for me while watching the other car come up on me than me come up on another car.
