If I understand what you mean correctly isn't it because there are two different and separate systems in the database, Becky? There's the numerical rating which Chalyse (I think) calculated from various studies plus the AHS associated survey (now defunct), and then there's the ATP member input which is separate and confined to "shows susceptibility" or "shows resistance" and only reflects the opinion of one individual. So it's not surprising that the systems may disagree.
