Oh but it does seem to.

Maybe somebody at the race teams should tell the engineers and team managers that a bunch of "google geniuses" on an internet racing forum says their cars are all the same and to quit wasting time and money trying to build cars for certain tracks.
They aren't building cars for specific tracks in the post-COT era. Fleet sizes are only half as big as they were 5 years ago.

If there were no gains to be made why do the top teams have huge engine programs?
Because they make their money by selling engines to small teams. Do you think Tommy Baldwin, Joe Nemechek, JTG, and Robby Gordon build their own engines?
