And currently, there is no team registration (that's coming in a few weeks). So I'm hoping that they make the event larger; 20,000 plus team entrants. And yes it was a fast event, but 4:09 is still VERY fast - that beat our Cat 2 team (4:20).
That plot of times is subdivided too finely. Do it by 30 minutes and you get a lovely smooth over-dispersed log-normal(ish) distribution. And if course there is digit bias to come under thresholds (5hrs, 6hrs...)
