They will not say anything more than I\'ve posted.They do NOT have people posted all over the track and the little I know, I had to pry out of them over a few of lunches(I always pay). There are only two guys, Ian and Warren (two POMMES, George) and I don\'t know if they have been given an OK by Track management, so I prefer nothing is said. They are not doing anything wrong.
I know the So Cal Whale and I hear he\'s a loser with an overall small positive return from rebates.Staying on point,you can bet your eyeballs that no-one has a system/equipment as extensive as they do in making variants.
On your statement that the posted cushion certainly matters in determining how fast the track is, you are not even close. The geeks told me that on 5 consecutive race days at Belmont Park in July, the posted cushion was 4in. During those 5 days the speed of the track varied from plus 40 to plus 160( from 2 to 8 lengths faster than par/norm) despite the posted cushion being the same each day.They know all about wind, maintenance etc.
The conclusion from people with far more expertise on variants than you or any other figure maker is that a posted cushion of 4in produced wild fluctuations in how fast horses run over the same 4in posted cushion on different days(same caliber runners) probably due to wind, moisture, maintenance.They did not feel their sampling days were an abberation as to what is the norm.
