Tangent.
Is it possible to find how many obs have 1, or 2, or 3 disagreeing IDs?
That more than two thirds rule racks up fast.
1 wrong needs 3 to convince - makes sense.
2 wrong need 5 - why not stay with 3 (especially if the second ID is simply NotAPelargonium - that should = a single disagreement)
3 wrong need 7. Such a pointless waste of IDs, that could have cleared 2 more!
