Miff-- just want to say that that is my kind of post. You did your homework, have a working hypothesis, and will check against future results.
By the way guys, I boxed 3 in the race, and the Dutrow horse was one. It did NOT look to me like he was doing much running the last eighth, especially considering how slow they were going-- the rail could have been a factor (haven\'t done the day yet), maybe he didn\'t want to go through the hole (looked pretty wide on the head-on), but I didn\'t see what you guys saw.
