Still, that photo-finish is a paragon of fairness and clarity compared with the Olympic marathon swimming, in which after swimming in the sea for 10k, it all came down to who could "strongly" touch one of a few small pads on a beam suspended above their heads on a raft floating on the choppy seas: in a finish where ability to obstruct an opponent without being penalised for it could count for as much as swimming speed and timing on touching the pad.
Remarkably the men's Olympic race produced (i) a gold medal photo-finish after nearly two hours that was so close that it took 15 minutes to figure out they'd initially named the wrong man as the winner and (ii) 2.2 seconds behind them, a three way photofinish for bronze (the third person to post that time was subsequently for disqualified for what he described as fighting off somebody that was holding onto his leg in the final sprint...)
The women's race saw the a silver medal photo-finish before one of the swimmers was disqualified for reaching over the top of her opponent to touch the pad first in a manner which looked a little bit too much like dunking
So if losing a rowing sprint by a couple of centimetres sounds tough, spare a thought for the person that is two centimetres away from touching a moving finish line whilst their competitor elbows them, after swimming for two hours to get there
