Good/decent article (http://www.speedsportlife.com/2008/10/01/avoidable-contact-17-cheating-nissan-bitter-porsche/ ):

"Let's take a moment to talk about lap times. Consider the following: Last year, I set the fastest Spec Focus lap at the NASA National Championships at 1:45.620. At this year's Champs, the best lap was 1:48.170, despite the fact that the Spec Focus rules now allow wider tires and lower suspension. Do you really think I'm two and a half seconds better than the best guy was this year, particularly considering that he was driving a better-equipped car? Of course not. Mid-Ohio was slow this year because it rained the day before and washed the rubber off the track, taking a couple of seconds off everybody's lap. Consider, if you will, that on a track the length of the 'Ring the equivalent rain-washing time gap would be nine and a half seconds. Lap times set on different days, under different conditions, simply aren't comparable. It's that simple. Some days are hot, some days are cool, some days there's rubber on the track, some days there's oil. The same competent driver, in the same car, might have a fifteen-second variation from one 'Ring session to the next. Think about that."



This seems to make the most sense...
