  "content": "<p>First, I would like to thank the organizers for putting together this interesting competition. </p>\n<p>I have a question about the data. I noticed that many events are quite short, even less than 1 second, with periods of no events in between. What do these events represent? Is it some data collection artifact, or are these real events, and what would that look like in real life? E.g., a person was turning normally, but then there was a half-second period of pathological turning and then normal again? Also, how accurate are the time stamps on these events? Was someone trying to pinpoint events to a tenth of a second, or is it more approximate? </p>",
