The old 'zero tolerance' rule strikes again. Honestly, 'trace' amounts are far below the theraputic level - they can have had no influence on the outcome of the race so are not the result of an attempt to cheat, which is what drug rules should be all about. Exactly the same case as Brass Hat in Dubai - each animal in question has a different rate of clearing traces from their systems and because these rates fall along a curve with a long tail, inevitably some will fall outside the vet's estimate - probably a Poisson distribution, maybe chi-squared?
