Fantasy Racers Should Want Qualifying Back
Fantasy-racing payoffs hinge on race outcomes. But if you are a fantasy racer — or a serious bettor — you could make money off qualifying. Not by wagering on it, but by using it as a data source. […]

One NASCAR Rules Package for All Tracks?
NASCAR wants to cut costs for teams by developing a rules package that, with minimal tweaking, provides good racing at any track. The 2019 rules package met with mixed results. Races were mostly better at […]

Sciencing Out NASCAR Rules Changes
Rules changes in NASCAR are tricky. There’s really no way to test them before implementing them. You’re relying on the judgement and experience of the NASCAR team, with input from race teams, drivers, Goodyear and […]

Are Cautions Really Going Down?
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. […]
