You've got something like 170 corners and none of those test drivers are ever going to be able to click off the perfect lap. They will always be giving up time somewhere.

Say the GTR vs. ZR1 internet wars... it was just ridiculous. I think the numbers published were around 2 or 3 seconds apart which when you think about it is less than 1% difference in time between cars. No one in their right mind would ever look at those two cars and say, "well, it's obvious that Car A is better than Car B."

IMO, you're better suited to put two cars on a much, much smaller track with a mix of low and high speed corners. That way you have the same conditions and only around 10-12 corners or so which will make it much easier to get a 100% lap in. Then you get a more accurate idea of which car is better.
