Michael, NO ONE can help you if you don\'t get what I have said on this subject, at tremendous length.
Kev didn\'t ask me whether it is slower, he asked me about what was done to the track. I know tracks are slower, as I have said a few dozen times, for all the reasons that enable me to decide on a daily basis whether tracks are faster or slower than they were the day before, and faster or slower than a track 100 miles away. Do you think I need to get cushion depth, soil composition percentages and hourly moisture content readings to do track speeds? Those are the primary things that affect track speed, and the various combinations of these things produce an almost unlimited number of outcomes-- but you MEASURE track speed by seeing how fast the horses ran over it, compared to how they ran over that and other tracks in previous starts. According to the head of Math at R.P.I. (who, by the way, used to play guitar for Commander Cody and the Lost Planet Airmen), the technical term for what we do is regression analysis.
That\'s what I do for a living, and there is no one who ever lived who has done it for as many racing days, or circuits, or faced as many varying conditions, or probably examined these questions as closely as I have-- if you haven\'t already done so, check out the audio-visual \"Changing Track Speeds\" on this site. It is ground breaking stuff-- you show me where anyone else has tried to tie science in with speed figures. You will see a quote in there from Dr. Mick Peterson, who is one of the scientists who have studied racing surfaces, saying he thinks that the way we measure track speed is a better way to do it than any purely physical measurements of the properties of the tracks. Just as the eminent scientist who wrote the Scientific American piece quoted in \"Are Racehorses Getting Faster\" said that accurate performance figures are the best way to compare generations.
Science, or as close as we can come to it. Not, \"I knew John Kennedy, and Smarty Jones is no John Kennedy\".
