So this is bracket racing, of which I am not a fan, but this is the equivalent of a hole-in-one. Its basically drag racing but you’re looking for consistency over who’s fastest. You claim a time, in this case a 10.55, and the closer to that time you are the better you did, but if you go any faster you’re out. So what OP’s pops has just accomplished is a perfect score. Not only did he get a perfect reaction time, which is hard enough, he ran exactly his dial time. 0.001 faster he’d be out. It was also mostly irrelevant since the guy he was racing jumped the start and was DQd immediately.
