"The article suggests that measurements would be taken at different locations on the track, rails & turns for example, after morning training & after the races were run, & that the results would "possibly" be given to the betting public as well as horsemen & track supers".

Not to be a contrarian which I have been accused of before. What happens on the days where the racing surface is changing throughout the day. I remember a day a few years ago at Churchill Downs, it was Tuesday during Derby week, where the racing surface changed three times. There was some moisture in the track from overnight rain and the track had been sealed tight as a drum because the expectation was for more rain.
The first race that day was a 4 1/2 furlong "baby" race that was won by Chilluki(?). She set a new track record and the track crew immediately "loosened" the racing surface. After about four more races the rain came pouring in and the track crew quickly resealed the surface. The end result was that the last five races were won in wire-to wire fashion, regardless of how quick the early fractions were run and the class of the horse setting those fractions.
There was another aberration from that day and it was the fact that Beyer gave Chilluki a 110 Speed Figure for her race, a number she did'nt come close to matching until late in her three year old season(at Churchill Downs I might add, hmmmmm).
Their analysis would probably be useful but it will still require the expertise of people like TGJB to properly quantify just how fast all horses ran on any given day, throughout the day.
