Hi Punter,
Maybe you must have misunderstood the intent of this thread, what i described in my posts were how I went about identifying the Class runners in each race.
My Class analysis provides only one of 4 crosshairs in the overall ability matrix.
Sorry i didnt explain, this isnt my Speed nor Pace method.

Shoto, what you have mentioned is so important, the method i outlined earlier measures the combined Class strength an the physical Track configuration which means its messy.

I turned to greyhound racing for some answers, as greyhounds perform more often than horses an go backward an forward from track to track.I built a large database of performances, what i was interested in was in quantifying the track to track adjustments then the grade to grade adjustments from track to track.

I built a whole set of Grade Par Times based on Grades, then i looked at Track to Track adjustments based on Track records an using a combination of MPS, linear regression an centripetal forces based on the physical layouts
.
Then i did a number of tests based on looking at greyhounds performances based on track to track avg's, single performance figures track to track (that is dogs only racing once at one of the tracks), performances that occured in 7 days , 14 days right up to 200 days between each performance, then looking at a 3rd performance or a return visit to the first track raced, then age analysis, as age degradation also impacts on greyhounds but in a shorter time span and finally Male an female comparrisons.

With that done if one was to look at the two major dog tracks in Vic the Class component from one track to the other is around .06 of a total of say .19 and this is where the Best of the best race from the state.

No need to say its valuable to know the class strenghts from track to track apart from the measuring the physical component of the track to track.
