>But there are countless degrees of pace between the obvious extremely slow paced races and normal or hot paced races, and all of these could affect final time to some degree that falls within what we consider a normal deviation for a race even if we think the track is basically staying the same speed-- so when we change the figure a little to make it fit tight that could as easily be because of pace as wind gusts, evaporation, track maintenance, etc.<

Thanks.

I think this a very major advantage of your figures as long as users are aware of it. (especially on turf)
