In microcosm, you can argue whether the racing is better with NASCAR's new Sprint Cup car or with the car that preceded it.
You can point out that lead changes in the second full-time season for the new car are down from last year and that individual races, in terms of laps led, have been dominated by one or two drivers - Kurt Busch at Atlanta, Kyle Busch at Bristol and Denny Hamlin and Jeff Gordon at Martinsville.
In a larger sense, however, there's no argument that - top to bottom - the Cup series is far more competitive this year than it has been since the Chase for the Sprint Cup was introduced in 2004.
If that seems contradictory, look at the numbers. After six races last year, four drivers were within 100 points of twelfth-place Clint Bowyer, as the race for the Chase already had begun to string out.
As of last Sunday's Goody's Fast Pain Relief 500 at Martinsville, the sixth race of the 2009 season, eleven drivers were within 100 points of twelfth-place Matt Kenseth, the number twelve being relevant as the final Chase-eligible position.
Last year, the 30th-place driver after six races, Jamie McMurray, was 246 points behind Bowyer. This year, David Ragan and Reed Sorenson are tied for 29th place, a mere 135 points behind Kenseth - less than one race's worth.
Admittedly, Bowyer was 175 points behind leader Jeff Burton at this point in 2008, as opposed to the 255-point advantage Jeff Gordon enjoys over Kenseth, but that's about the only instance where the field was tighter last year.
Whether more teams have gotten a handle on NASCAR's new racecar, or whether the ban on testing at NASCAR tracks has prevented the more well-heeled teams from perfecting the refinements that might give them an edge over the competition, the Chase appears more wide-open than ever this year.
"I think it's a little bit of both," said Kasey Kahne, driver of the #9 Richard Petty Motorsports Dodge. "Everybody has had a lot of time with this car now. To me, it seems to race better with other cars, and other cars around us seem to be racing better with this car.
"I think that's trial-and-error and making good improvements. I think the testing (ban) has probably helped that also. You see the good cars even have some bad days, and to me, that's kind of cool to Jimmie Johnson not to be the fastest guy every week - just some of the weeks. So hopefully it keeps working this way, and it'll create a championship run and a good points battle, and you'll have a few different winners throughout the year."
