This multi-million dollar investment by NASCAR to have a smorgasbord of statistics above and beyond the traditional notions of start and finish position, top-5, top-10, wins and poles is a statistic geeks wet dream.

Loop Data driver ratings are routinely mentioned in driver articles on team websites and in the more NASCAR-centric media. But, beyond rattling off one of the dozen or so metrics the particular driver in the article excelled in, Loop Data remains somewhat of a lofty concept to most NASCAR fans and even NASCAR fantasy game players (who should be eating it up. Or, should they?)

  • Average Running Position: Sum of driver position on each lap – divided by the laps run in the race.
  • Box Score: A summary which shows key statistics to give a complete picture of the drivers’ performance throughout the race.
  • Closers: The number of positions that a driver improves over the last 10 percent of the race.
  • Consecutive Laps with a Pass: Number of consecutive laps with at least one pass.
  • Consecutive Passes without Being Passed: Number of consecutive passes without being passed.
  • Fastest Drivers by Straightaway: Ranks each driver by average speed on each straightaway.
  • Fastest Drivers by Turn: Ranks each driver by average speed in each turn.
  • Fastest Drivers Early in Run: Ranks each driver during the first 25 percent of laps run in a typical full green flag segment.
  • Fastest Drivers Late in Run: Ranks each driver during the final 25 percent of laps run in a typical full green flag segment.
  • Fastest on Restarts: Shows average speed on the first two laps under green flag conditions.
  • Halfway Home: Compares the race standings at the halfway point of the race with the final results.
  • Laps Driver Improved Position: The total number of laps during a race where a driver improved his position.
  • Passing Breakdowns: For each driver, shows how many and what percentage of passes were made by each turn and each straightaway, including the total number of passes for each driver.
  • Quality Passes: The number of times a driver passes another car that is running in the top 15 while under green flag conditions.
  • Speed in Traffic: The speed when there is another vehicle within one car length under green flag conditions.
  • Time Trailing at Finish: The time behind the leader that each driver finished behind the race winner. Average green flag lap time is used to calculate cumulative time for drivers not on the lead lap.

NASCAR Driver Rating is a formula that combines: Wins, Finishes, Top-15 Finishes, Average Running Position While on Lead Lap, Average Speed Under Green, Fastest Lap, Led Most Laps and Lead-Lap Finish.

A NASCAR driver can score a maximum driver rating of 150 points per race. Also, the driver must have raced in 75% of the scheduled point-paying races.
