How did Pricsilla Lopes-Schliep win the bronze when she was tied with Sarah McLellan with a time of 12.64??

Question

The Canadian hurdler Priscilla Lopes-Schliep won bronze even though she was tied with McLellan. How was it determined that she got the bronze and the other girl got the silver?

Answer 1

There is a camera placed at the finish that takes ~2,000 pictures a second. It's incredibly accurate. The official times are given in hundredths of a second, while the camera can decipher thousandths of a second. Therefore silver could have been 12.641 and bronze could have been 12.643, but both would be listed as 12.64 despite silver going a thousandth of a second faster than bronze.

Answer 2

They have a special camera that measures hundreths of a second so thats how she got the gold medal.
