The National Sprint Car Championship is your source for an analytical determination of the best 410 Sprint Car Driver in the United States, across the All Stars, World of Outlaws, and Knoxville Nationals.
The analytical methodology used to determine the National Sprint Car Championship aligns with "Least Square Means" / "General Linear Models" (click here).
Let's pretend that there are two races.
Here is the finish of the first race.
- Nancy (200 points).
- Kevin (150 points).
- Todd (120 points).
Here is the finish of the second race.
- Kevin (200 points).
- Mary (150 points).
- Todd (120 points).
The two races are "Crossover Races", because two of the tree drivers are common in each race. Notice that Kevin > Todd in both cases. In other instances, Kevin > Mary and Nancy > Kevin.
A GLM model (Generalized Linear Model - as mentioned above) determines mathematical coefficients for each race (helping us determine the strongest fields/tracks during the season), and the methodology determines the mathematical coefficients for each driver. The mathematical coefficients are called a "KPI" or "Kevin's Performance Index". In our example above:
- Nancy with a KPI (Kevin's Performance Index) of 92.5.
- Kevin with a KPI of 55.0 points.
- Mary with a KPI of 17.5 points.
- Todd with KPI of 0.0 points.
If there were only two races during the entire season, then Nancy would be declared the champion, as her KPI would be greater than any other driver.
In a traditional point system, Kevin would be the champion, because he participated in two races whereas Nancy only participated in one race.
- Kevin = 350 points.
- Todd = 240 points.
- Nancy = 200 points.
- Mary = 150 points.
But we can easily see that in the one Crossover Race where both Nancy and Kevin participated, Nancy beat Kevin. The methodology rewards Nancy, giving her a higher KPI than Kevin.
The unique nature of this methodology rewards drivers who do not participate in every race, yet outperform comparable drivers in "Crossover Races". By using this system, a driver like Rico Abreu or Christopher Bell is rewarded for driving a minority of the races but outperforming those they compete against. Similarly, the system rewards drivers like Donny Schatz who outperform those they compete against on a weekly/daily basis. Repeated outstanding performance is rewarded in this system. Racing in every race within a series is not required.
