I also want to add in the context of human sprinters & F1 drivers, their reaction time is measured via leg actuation, which for a creature evolved to be an object-throwing endurance hunter is going to have worse neural & muscular latency than, say, your forearm. That is why using your finger to trigger a response in a conventional computer time tester can get such high speeds, cause we're essentially evolved for it.
