Tuesday, June 24, 2003 More legs, same result...People I have enormous respect for, like Kent Olsson, have said that booms are most common at certain parts of a course (Olsson says the first and next to last controls are the places people miss a lot). So when I looked at split times a couple of days ago, I was surprised to see booms distributed more-or-less evenly.At lunch today, I decided to look at some more races....and the result was the same. I've now looked at a total of 8,036 legs (i.e. chances for booms) and 1,474 booms.* The booms are distributed pretty evenly among each quarter of the race. Maybe it is common knowledge, but it surprised me. I'd expected more booms in the last quarter of the race (when orienteers are getting tired). In looking at results there is a very clear tendency for certain legs in specific races to have a lot of mistakes. In a specific race you'll see a very high boom rate on one or two legs. Presumably those legs are especially tricky. Could I look at a course and predict which leg would be trickiest? I'll have to try that some day. * I'm using the default in winsplits to identify "booms." Actually, winsplits doesn't identify a "boom." Winsplits just looks at the time used on a leg. As a result, a runner who has a slow leg, even if they don't actually make a classic boom will be highlighted as having made a mistake. Maybe they just ran too slowly or took a bad route. posted by Michael | 8:12 PM
