I did some number crunching at lunch, so for those of you NOT on Facebook... (I mean you Twinz :p ) here you go
In a class of 65 competitors....
On day 1, there were 47 gaps that were less than 0.1 seconds, and 9 that were less than 0.01 seconds, including one dead tie (Matt Hugenschmidt and Brad PJ Moore)
On day 2, there were 49 gaps that were less than 0.1 seconds, and 13 that were less than 0.01
Overall, there were 38 gaps that were less than 0.1 seconds and 6 that were less than 0.01. The smallest margin was Daniel Fryer over Bernie Kaeferlein by 0.001.
