I have been an auto racing fan since the mid-1990s. The first race I watched was the 1994 Pepsi 400, where Jimmy Spencer won his first career NASCAR Winston Cup race. The first open-wheel race I watched was the 1995 Indianapolis 500, the final Indy 500 before the CART/IRL split. I became a really passionate racing fan in 1997 and purchased a NAPA Almanac of Stock Car Racing, from which I compiled reams of NASCAR statistics. I founded the Pace Car Challenge weekly game on the Motor Racing Network forum (when it was called SpeedFX), and briefly wrote statistical columns for the now-defunct HK's Race Day site and Stock Car Review. This culminated in my website,, for which I have entered every Formula One, NASCAR Sprint Cup/Nationwide/Camping World Truck, CART/Champ Car, IRL/IndyCar, American Le Mans Series, Le Mans Series, MotoGP, and Grand-Am Rolex Series race. I invented two new racing statistics on my site that had not been used before, average percent led, a self-explanatory statistic which is the best possible measure of racing dominance, and percent beat, an equally self-explanatory statistic measuring consistency. These statistics allow more direct comparisons between drivers in different eras or even different series. Recently, I started a monthly column for Motorsports Analytics where I created several other statistical metrics.
