I counted how many times Andersen looked at the map when she was shown on the video. I also kept track of how many seconds she was on camera. I could see her well enough to count how many times she looked at the map for 1:45. During that time, she looked at her map 24 times. That's roughly a look every 5 seconds.
Watch Andersen carefully and you'll probably notice two things. First, she looks at the map a lot. Second, she runs fast. Actually, you might also notice a third thing...those orange number bibs make the orienteers look like fast moving deer hunters.
