NASCAR’s Loop Data are statistics generated from electronic scoring loops embedded around each track hosting races in NASCAR’s three national series – the NASCAR Sprint Cup Series, NASCAR Nationwide Series and NASCAR Camping World Truck Series.

Here are explanations of some of the different categories.

Number of Fastest Laps – How many times a driver had the fastest lap of all drivers
Green Passes – Green flag passes for position
Green Times Passed – Number of times passed under a green flag
Passing Differential – Total passes minus number of times passed under a green flag
Quality Passes - Number of times passing a car running in the Top 15 while under a green flag
