Well, remember that the official times are some form of aggregate of hand and manually started laser.
So the 4.24 was undoubtedly the time of one single timer using a stop watch who immediately reported his result up to the analysts. The official 4.43 is then, presumably, the result of the fact that that particular individual with the stop watch was quick to stop the time. I suspect that 9 out of 10 qualified timers had Taylor in the mid to high 4.3 range on their watch and this weighed against whatever the laser said is what yielded the official 4.43
Alternatively, as one example, whoever hand timed Dorin’s 40 was obviously much closer to the laser time because his official time of 4.40 remained the same as the unofficial time that posted immediately after he ran his first 40.
It’s definitely an academic scenario due to so much room for human error on both the stop watch as well as the manually started laser systems.
Regardless, these guys are fast and it;s impressive to consider their movement rates weighed against their bodymass.
