Racing:

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 despite getting away with using an illegal intake manifold. 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 was primarily a NASCAR fan in the late '90s and early 2000s, but eventually became more of a general racing fan. I founded the Pace Car Challenge weekly game in 2000 on the Motor Racing Network forum when it was called SpeedFX (although the forum no longer exists, the game is still hosted to this day on RacingStalkers), and briefly wrote statistical columns for the now-defunct HK's Race Day site and Stock Car Review. This culminated in my website, race-database.com, 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, Grand-Am Rolex Series, Tudor United Sports Car Championship, and Formula E race. I invented several 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, cumulative races led, which converts average percent led to a unit-free career total, percent beat, an equally self-explanatory statistic measuring consistency. These statistics allow more direct comparisons between drivers in different eras or even different series. In 2013, I briefly wrote a column for Motorsports Analytics where I invented several other statistical metrics, including natural percent led (which measures dominance based solely on on-track lead changes as opposed to dominance after inheriting the lead due to pit stops or other drivers' misfortunes) and fastest lap percentage (a better measure of raw pace) before creating my own advanced racing statistics website racermetrics.com early in 2015, where I followed up on some of my ideas from Motorsports Analytics as well as coming up with some additional ones.
