Baffert admitted that Gamine was treated, my point is setting thresholds that low, there is no room for error in withdrawal times.
I think surveillance, with meticulous record keeping which should be made public, along with testing , should be considered when reviewing a test. Assuming that like humans, every horse is different in its metabolism and how they process medication. Some humans need more meds than others, as in larger doses.
Just for comparison , if a human smokes some weed, the withdrawal times vary greatly from person to person. It stands to reason that the same would happen in animals.
