More accurate result times than just to the second

Why don't the results have times to the hundredths? All results only go to the second?

@topro Yes, you can measure times to hundredths of a second, but that ends up being kind of meaningless with chips. It's impossible to say exactly when a chip will be picked up by the sensor (this problem is worse with bib chips than with shoe chips, but it's a variable with either). Almost certainly, either type of chip will be picked up by the sensor [i]before[/i] the runner crosses the finish line. So, you can make a very solid case for rounding all cross country times up to the next nearest second. The timing method really doesn't admit of more accuracy than that. Hope that helps.

Thanks Coach, The St Vrain results today are puzzling. A lot of "ties" because of only going to the second. 1st and 2nd tied. 3rd and 4th tied etc. They did have chips on their shoes. So the chip gives a result before the finish line? Just would like to see the margin of victory.

Running Bear Timing, the timing company for the St. Vrain Inv., use a FinishLynx camera to check close finishes and make sure the results get it right. About 5% of the time, close finishes are not accurately judged by a shoe chip, so Benji Durden looks at the chip results, and then goes back through the close finishes to see which runner's torso made it to the line first and makes sure the final places are accurate. FinishLynx cameras are accurate to a thousandth of a second.
