All-Time Pro Stock Tour Driver Rankings by Performance Score (Just for fun!)
October 3rd, 2023
Disclaimer: This is intended entirely for fun, it doesn’t represent a true ranking, it’s not meant to be taken seriously. I created a basic equation model to calculate an “MFS” ranking for a big handful of many of the most prominent/prolific drivers (Multi-Factor Score). Basically: I factored in wins, top-5s, and top-10s in different weighting, to reward both wins, and consistency of different tiers, and then contrasted it to total number of races, to account for sample size effects. PS: This is strictly for Maritime Pro Stock Tour, though I would love to add in MASCAR stats. So, for example, this only accounts for Wayne Smith’s time in Pro Stock Tour sanctioned races.
I may re-visit this, incorporating championship points, average field size raced against, average finishing position, etc. Also, over time of course, many of these numbers would have fluctuated up or down for these drivers, to get to where they fall now.
The simplified Multi-Factor Score (MFS) model:
MFS = (Win% × 0.5) + (Top 5 Ratio × 0.3) + (Top 10 Ratio × 0.2)
The model awards both wins, and consistency with different weightings.The problem with this model in this format, is that it awards win %, Top 5 Finishes %, and Top 10 Finishes %, but it doesn’t account for number of races. So, Cassius Clark and Ashton Tucker for example would be way up at the top of the rankings. Their statistics are fantastic, but the sample size is much smaller than some other names. To ameliorate this flaw, I introduced a sample size modifier to account for number of races. I took the natural logarithm (ln) of the total number of races and used it as a multiplying factor to slightly adjust the MFS for each driver. This gives more weight to those who have more races under their belt, without overshadowing the other metrics entirely.
The modified formula for the MFS would be:Modified MFS = MFS × ln(Total Races)
Example:
Cassius Clark
Total Races: 24
Win % = 8/24×100 = 33.33%
Top 5 Ratio = 18/24×100=75%
Top 10 Ratio = 18/24×100=75%
MFS = (33.33×0.5) + (75×0.3) + (75×0.2)
MFS = 16.67 + 22.5 + 15
MFS = 54.17
Modified MFS = 54.17×ln(24)
Modified MFS = 54.17×3.1781
Modified MFS = 172.27
The fun stuff!
