I ask because I believe, maybe incorrectly, that the confirmatory test confirms the first test by being within it's error range. Not by also being a positive test. May I demonstrate by some totally made up figures. Lets say that 35.0 is the allowed maximum. If a test comes back as 36.2 +/- 1.0 then that is a positive as the possible range is 35.2-37.2. If the second test comes back as 34.9 +/- 1.0 then although that is a "negative" test it actually confirms the first test as its range of 33.9-35.9 overlaps the first test. I also believe that the combined tests narrows the actual result to 35.2-35.9. Still a positive test even if you look at it that way. I don't believe it is simple as first test positive, second test negative, lets just give him a light penalty. In other words the more testing that is done of samples taken at the same time the more precise the test becomes. Again. I may be completely wrong on this. I suspect triplev123 has more accurate information on this topic.
