Richmond Redux: Relative Velocity

NOTE: Some clarifications added 1:00 p.m. 4/30/12. Thanks to all the commenters, especially @nateryan! I think Dave Moody did a good job breaking things down. The situation is confounded because there were so many different […]

Cautions: A Historical Downward Trend Over the Last Six Years

Being the data geek that I am, I was really curious if the decreasing number of cautions was specific to this year. It’s not: Cautions have been decreasing since 2005,as the graph below shows. The squares are the cumulative number of cautions per 100 miles, obtained by adding up all the cautions in a season and dividing by the total number of miles in the races. (This is a more accurate number than total cautions, given rainouts, shortening races and different venues from year to year.) […]

More Ragan vs. Allmendinger Statistics: Running at Finish

Great comment from Robby on my post statistically comparing AJ Allmendinger and David Ragan:

Ragan’s low finished were often a result of a wreck. AJ’s bad finishes were generally the result of bad handling cars or bad luck (Dover, Indy, Texas). […]

100 Million vs. 78 Million is not the Numbers Question for FOX vs SPEED

The NASCAR pundits have again simplified a complex situation. Incorrectly.

I’ve heard the argument over and over, in print and on radio that this is a bad idea because EPSN is in 100 million homes and SPEED is in “only” 78 million homes. They argue this would be a decline of 22 million potential viewers. The question not being asked how many of those 22 million ESPN watchers are actually potential viewers? […]

How Mobil1 Goes in a ‘Quaker State’ Engine

Got a number of questions today about how a team that uses Hendrick engines – Hendrick having Quaker State as a sponsor – can have sponsorship from another oil company. The questions were along the lines of “Will Stewart-Haas have to drain the oil pans when they get them from Hendrick?” Here’s a quick answer, since I’m in the middle of a cross-country move and just about everything I own is in boxes: […]

A New Trackside Sign: Speech Limits

Jenna Freyer of the AP reported that some NASCAR drivers have been fined recently for negative comments about the sport. She wrote:

“The Associated Press has learned that NASCAR warned teams during the offseason that public criticism of the sport would no longer be tolerated, and at least two star drivers have been fined — one as much as $50,000 — for comments that were deemed destructive to the industry.” […]
