Stats

This race took place before 2020 and may have incomplete data.

Stats on this page
  • ARP - Average running position
  • wARP - Weighted average running position - A driver's average green flag running position, which each lap weighted in proportion to how well that lap predicts a driver's finish position over Lap Raptor's entire data set. The result is that a driver's running position in later laps are weighted higher than earlier laps. This better accounts for strategic decision making and smart driving (for example, earlier in a race you might be willing to sacrifice track position for speed or to avoid on-track incidents).
  • GF Laps - Green flag laps
  • SS - Speed score - 1000 x the ratio of the driver's 95th percentile lap to the race 95th percentile lap. A good read of a driver's top speed. [Read more]
  • GR - Gain rating - The weighted number of positions gained. The weighting is done based on the perceived difficulty of passing from a driver's current position. For example, it's for more difficult to pass from 2nd than it is from last, because the quality of car and driver is much higher at the front and there's just fewer spots to gain to begin with. The driver is assigned a score for each lap on which he or she gains a position. That score is the product of two values: the difference between the driver's starting and finishing position on that lap, and the weight of their starting position. The weight is inverse to the ordinal value of the position; something like 1/N, where N is the position. For example, 12th has a weight of 1/12 [Read more]
  • LR - Loss rating - See GR, but LR is only for laps where the driver has lost position. The weight is the inverse of their position from the back of the field, i.e. losing positions at the rear of the field results in a higher score than losing positions at the front, and thus a higher score is bad [Read more]
  • GR-LR - Net rating - The difference between the driver's GR and LR [Read more]
  • POMS - Percent of max speed - Race adjusted average speed. Assuming the fastest lap of the race is the fastest anyone could have gone on that day in that race, each lap speed as evaluated as a percentage of that lap speed and averaged to gain the driver's race adjusted average speed. This stat exists because without it, it's impossible to compare laps between a low speed track like Martinsville against a high speed track like Talladega. Note that this still isn't perfect: some tracks have greater fall off than others, and sometimes the weather changes or there's a rain delay, and that can cause distortion in POMS.
  • cPOMS - Continuously graded POMS - Like rPOMS but instead of using the fastest lap of the race, it uses the fast lap of that lap. For example, when scoring a driver's lap 30 lap speed, it uses the fastest of all drivers' lap 30 lap speeds
  • PGAE - Positions gained above expected - For any given running position, we can find the average position on the next lap. PGAE is the sum of the difference between the corresponding average to the driver's current running position and where they ended up in actuality on the next lap. For example, if a driver is running in 12th, and a driver in 12th on average is running 11.95th on the next lap, and the driver actually gains a position, he is scored a 0.95 for that lap. But if he held his 12th instead, he'd have been scored a -0.05. PGAE/100 is the driver's average score per 100 green flag laps
  • PFARP - Positions finished above running position - Like PFAE and PGAE, but comparing the driver's finish position against the average finish of a driver at their current running position at the specific point in the race. For example, if a driver is running 12th on lap 100, and the average finish for a driver running 12th on lap 100 is 13th, and the driver finishes 6th, they score +7 PFARP.
  • wPFARP - Weighted positions finished above running position - Like PFARP, but the the laps are weighted based on how well that point in the average race predicts a driver's finish position over Lap Raptor's entire data set. See wARP for more information.
  • ΔPOMS - Change in POMS - How much faster a driver went in the final segment than in the first. Last segment minus first segment.
  • 1st Seg Stats - First segment stats - The same stats as you know but only before the first caution or pit stop of the race
  • Last Seg Stats - Last segment stats - The same stats as you know but only after the last caution or pit stop of the race
