If Logan Gomez and Alex Lloyd raced anything besides Indy Pro Series cars, their close finish at Chicagoland Speedway on Sunday might have been ruled a dead heat.

Gomez beat Sam Schmidt Motorsport team-mate Lloyd to the line by 0.0005 of a second - or about 1.65 inches at 188 mph - to win the Chicagoland 100 in the closest finish in Indy Racing League history. Fortunately, the League added a fourth decimal point to its timing and scoring system in 2001, becoming the only motorsports sanctioning body in the world to score to ten-thousandths of a second, otherwise the pair would have been hard to split.

A high-speed camera supports the system by taking pictures of the start/finish line every ten-thousandth of a second, confirming that Gomez and Lloyd had indeed beaten the previous closest finish in the Indy Pro Series - the 0.0170secs that split Mark Taylor and Ed Carpenter at Chicagoland in 2003. To widen the scope of the result, it takes a tenth of a second for a human eye to blink and a hundredth of a second for a hummingbird to beat its wings.
