Turns out they're pretty proud of the tech that produces such funny looking peoples :)

 

the camera Scan 'O' Vision MYRIA, captures better quality images, around 10,000 digital photos in a vertical line per second.

When they cross the line it show Mahe 2nd but Croatian PF. I would have assume Mahe should be 2nd. If it's a photofinish shouldn't Mahe also shown PF not 2nd.

Should have been joint gold. A 0.00001% parallax error could mean silver to mahe. That is just wrong and unfair for the croat.

I doubt Mahe would have minded sharing a gold medal, however, today I read that in some events they can calculate down to 1 millionth of a second.

Maybe that was an error, as I saw another race which was a photo finsh, and it showed 1, PF, PF. So this one should have probably been PF, PF, 3. Everyone thought the other guy had won, as he was leading, but it was all about the timing and the surge, which worked in Mahes favor. He was very lucky IMO that it worked in his favour. Save

Touch of a metal pad in the pool. Whatever time frame you want to put it's ok, it's stationary.

A straight line across 9 lanes of a track is easy.

A straight line across a giant lake??? You've got to be serious about getting it so right to 1mm for the winner.

I don't think a straight line (e.g. laser) across a lake is that difficult. It's not a "giant" lake, although maybe 100m across as opposed to 10m for a running track.

 

But if you're going to be this accurate on the finish line, then you should have the same accuracy at the start positions. And the start and finish lines must also be absolutely parallel. And the boats must be exactly the same length.

 

And natural variations (e.g.) wind from one lane to another could cause that much time difference... so now the medal is awarded to the lucky guy as opposed to the fastest.

And I believe this is why the fastest qualifier gets dibs on the best lane. Certainly in swimming the fastest qualifier gets lane 4 because that is the best lane for both wakes and keeping tabs on the opposition.

And 'short stroking' so that you are on the power phase of the stroke crossing the line is what Drysdale said he did, and that's what won him the race.

itxtme: But why is is Mahe's number distorted!?

 

 

 

In a photo finish camera the camera "frame" is a vertical line one pixel wide. The image above is a composite generated by displaying successive vertical frames. The number on Drysdale's boat is longer because it appears in more finish frames. That means it was passing the finish frame a much SLOWER speed.

 

Or to put it another way, the picture is a time sequence, with time going from right to left.

Where/How do you put the points in the lake such that they do not move at all with the waves?

Wow that's a very harsh call. He was fastest if he crossed the line first, it's that simple. If you want to start accounting for variables, you could contest lots of results. 

 

The fastest guy won, even if it's by a tiny margin!

A pole to the bottom?

Why in the lake? Why not on the banks? If you insist on in the lake, then on poles stuck into the bottom of the lake.

Surely the whole point is to find the best athlete? And that's not necessarily the guy who got from start to finish fastest, if that guy received significantly more assistance from the elements.

So you want indoor rowing? 

 

The best athlete is the guy who finishes first, if the race had been longer or shorter, perhaps a different result, but then you need to set it at some length.

 

I am not really sure what you are arguing in favour of here?
