Brisnet numbers are made by computer, and rely heavily on averages. That day featured a track that went from muddy early to sloppy for the last four dirt races. It also had a lot of wind, which was changing speed and direction all day. The race in question had a 5 furlong straight run to the turn-- gusts can affect the time a lot in situations like that.
There is no question the track got MUCH faster starting when it was designated as sloppy, the only question is whether it continued to get even faster than that by a couple of points later in the card, as I had it. A computer that relies on averages (or those that don\'t believe tracks change speed, or have rules about how much they are allowed to have them change race to race) have to have that race faster based on methodology, not judgment. Whether I got it right remains to be seen.
Additionally, by memory, the top two were in light and saved ground, which will make them come up fast on pure \"speed\" figures relative to those that factor in weight and ground.
