I love the Gen-6 car. Not as much as I love the Nationwide cars (but that’s got more to do with what I drive than it does the cars). The big question is whether the decrease in cautions is going to be changed because of the new car.Let’s start (as we usually do) with the new car. […]
At the start of the season, the big news was that cautions were remarkably down from last year. As I showed, this isn’t a new trend – it’s a continuing trend since 2007. Since the season’s data are now complete, I thought it was time to revisit the data. […]
This was the first year that most people noticed a decrease in the number of cautions, but (as I’ve pointed out), 2012 is merely the latest in a six-year trend of decreasing cautions. The same downward trend is evident in the Nationwide Series. This year is perhaps notable for it being so extreme.
The data clearly shows the trend: The question, of course, is why?
ust out of curiosity, I decided to do a similar analysis on the Nationwide Series caution record as I did on the Cup record. My intent was that if there was something specific to the Cup series – the new car, the Chase, etc.), it would show up because the Nationwide would follow a different trend. Not at all! Remember that I’m plotting number of cautions per 100 miles run […]
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.) […]
I honestly cannot help it – scientists are naturally skeptical. If you make an assertion, I will have to question you on what data you have that supports it. This is second nature to the people I work with, but I realize it is damned irritating to non-scientists (aka “normal”) people.
So when I started reading everywhere that “cautions were down 35%”, I had to go look into it. This is a preliminary post – more detailed analysis will follow as soon as I’ve read my students’ final projects and gotten comments back to them. […]
