NASCAR 2018: The Year in Charts and Graphs

This is the time of the year when everyone takes one final look back at the last year before turning to think about the new one. So, in this last blog of the year, I thought I’d summarize the season in charts and graphs. […]

Early-Season Predictions Require Caution

Predictions: The Peril of the Early-Season Off-Week I can post only when I have something to contribute. The professionals who cover NASCAR don’t have the luxury of waiting until there’s news. The content monster remains perpetually […]

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.) […]
