Very sound reasoning in constructing your figure. The only problem is that leaves Ginger Punch with a 92 BSF. While it is possible that she scored a 6 length victory at a 92 figure, I think that it is unlikely. I believe she ran a slower than normal figure, but 12 points is quite a regression in a winning effort.
The question this poses is whether or not the timer was functioning properly in both races. Steven Crist (
