I didn't realize on Sunday that the article you were waving at me was one you wrote. Too bad you couldn't stay Monday to see the race Gary Sciacca arranged to honor Steve's mother. Very touching.
Hard to disagree with your basic points, but my take is that the current system is not the endpoint, but one always has to start somewhere. If enough tracks buy into the concept, then it should be a lot easier than it is now to impose stricter testing and disclosure standards which apply on something approaching a nationwide basis, assuming bettors actually support the tracks with the best testing and detection.
P.S. I can't guarantee this chart is completely up to date, but if not I'm pretty sure takeout information also appears with the pps in the drf:[
