Ok, I got it. So basically the only way (as far as we know with the test available today) to get affecteds is if the "breeder" either don't test prior to breeding or breed affecteds and carriers together, and not using a clear in the mix.

Right, Affecteds and Carriers and IND (between a Clear and a Carrier, so should be considered a Carrier) should only be bred to Clears, period

With the very, very few inconsistant results excluded, looking at the test results, what we are seeing is what we would expect to see, especially in looking at tested sires and dams and then their offspring.
