Unbelievably close difference between Gold and Silver. 

 

This means there was 5mm of Mahes' vehicle over the line more than his competitor, over a 2000m course. (Hopefully our math was correct).

 

Apparently the smallest margin between 1st and 2nd in Olympic History.

 

Wondering how they worked it out. Even a 240FPS Camera was unlikely to capture that difference, and if it was sensor based, you can't understand them taking sooo long to work it out. 

 

Out of interest could they have awarded 2 golds? What then happens to Silver and Bronze? Are there 4 "winners"?

 

Well done to Mahe and to Croat Damir Martin

What a finish, I thought he was done, but as he said, he 'chucked in a couple of short ones' and just nosed it in. Closer than the Evers-Swindell win in Beijing..

 

If they had awarded 2 golds, I think Silver would have been missed out, and the Bronze would have been awarded as per normal. Thats what they do in the swimming (been a couple of dead heats there for second and they award the number of medals that should be awarded (ie. 3) and the next down misses out). In the case where more than 3 dead-heat, as in the swimming when the Singaporean beat Phelps - there were two other swimmer on the same time as Phelps, so the Gold went tot he Singaporean, and three Silvers were awarded - no Bronze.

They have given out more than one silver in the swimming, there were three I think in one race!, and still gave out the bronze as well.

 

Edit: I'm sure they gave the bronze out as well?

Theres been a couple of dual awards this year already. Interesting they were able to find a difference, else both would have been awarded.

 

Comes up when there is a first equal, womens swimming had a couple. They skip silver, both got gold and there was a bronze following.

 

Under the Olympics' scoring rules, when two athletes tie, they each get a medal — meaning that while this race has two gold medalists, no one gets a silver. Instead, Sweden's Sarah Sjostrom won a bronze medal after finishing 0.29 behind the winners.

Wow. Interesting article.

 

I'm astounded that there could be 3cm difference between 2 lanes in the same pool. Or does a 3cm tolerance mean that potentially there could be 6cm difference between 2 lanes?

 

I can understand the pool concrete expanding and contracting with temperature and so on, but I'd have thought it would be reasonably uniform. And that the water and air temperature in an indoor pool would also be quite well controlled, again ensuring control of the expansion/contraction. And that the pool could then be constructed to be exactly the right size and shape at some specified water and air temperature.

Although they did have the same time, the photo finish did show Mahe just ahead. Although he was very lucky as is all came down to the timing of the last stroke because the other guy was ahead of him, and had caught him up, and you would almost put money on the other guy having won if you had seen it in realtime. That is what sport is all about, sometime you win, sometimes you lose. Very similar to Valeries throw, noone thought she would lose up until the second to last throw. Then she was left having to play catchup, which was almost impossible.

But why is is Mahe's number distorted!?

Angle, lens curve, lighting, reflection, any number of things I'd expect (having discussed this very photo with a photography nut here).

You think thats distorted, take a look at the running race finish shots! It seems to be a rotating camera, so the images get stretched as its not quite in sync with the rotation of the beam.

 

Preeettty sure legs don't look like this on humans (not a rio pic but same technology)

But the question is when we are talking such small amounts of movement is the augmentation taken into consideration, and if so to what degree of specificity do they have it set to.  These are big distances too, the camera is not right next to these two boats.  I dont know the answer, but it begs the question right?

Motion blur I expect.  Remember the boats motion is a reasonably constant speed of momentum plus a periodic pulse/surge of motion with every stroke.

 

Mahe won by pure luck of being on a pushing forward stroke motion at the very time he crossed the line. 

 

 

 

The image looks fine for me otherwise.  Barrel distortion etc wouldn't come into effect over such a short distance, and it if did then it's clearly not the camera/lens combo for the job.

You can imagine, though, that if it's a digital camera and scanning from top to bottom, that Mahe's boat is actually *another* 5mm ahead than it appears in the photo.
