Yeah, I agree with Jesse. It is always hard to compare someone's times against someone else. Even if the two cars are reasonably close to being "prepared" for their class (such as me vs. Jesse), you still have dependencies on the strengths and weaknesses of each course-car-driver combination.
Perfect example: My GS Subaru (and myself as a driver) tended to do really well on high-speed concrete with fast transitions. I didn't have too much trouble trophying at my first couple ProSolos at Ft. Myers and did quite well at my last one considering the class had some tough competition. But every year at the Petersburg ProSolo, which was a comparatively low-speed course on asphalt, I got OWN3D two years in a row by essentially the same people. Last year, after trophying Ft Myers, I only managed to stay ahead of Katie, one other driver, and a newbie on Falkens at Petersburg. Yeah, I think my driving was off a little, but I don't think it was bad enough to expain that result. :o
But I do see where you're coming from. Competition is FUN no matter what kind of car/course/experience you have. PAX-based results are about the best handicapping method you can use, and are interesting to play with. They ARE proven to be somewhat accurate if you look at average results over the course of the year and across a good variety of courses, but just make sure you don't make them into more than they are.
