Stroker + Aubrey's season

Well let's compare how they did going by all the races in the movie.

Aubrey wins the Daytona 500, Stroker gets a DNF.

Stroker hooks up with Clyde Torkle & wins the next race, Aubrey finishes 3rd.

I think the Talladega race is next, Stroker gets another DNF, I'm assuming Aubrey wins that race, but we never find out.

Right after that, in the hotel scene, Stroker is on the bed reading the Nascar Grand National magazine, and on the cover it reads "Stroker Ace wins Atlanta."

Right after that they show the end of the Michigan 400 race where Aubrey wins and Stroker finishes 2nd.

Then in the Chicken Pit montage thing near the middle, they show Stroker in victory lane at the North Carolina speedway.

And finally at the Charlotte race at the end, Stroker wins, and Aubrey finishes in 2nd.

From what we see & hear about, I guess it's pretty even, although Stroker gets the edge.
