2 incorrect IDs and 1 correct ID wouldn’t create a maverick ID.
I think! (unless my memory is failing me 
)
so your description (“to simply disregard IDs marked as maverick as a disagreement entirely”) wouldn’t be impacted in this scenario.
It would take 3 incorrect IDs and 1 correct ID to create a maverick.
In which instance the correct ID already has no power - until someone else seconds it.
However, in the exact inverse of the original post we would see some loss in power.
e.g. at present if we have 3 x incorrect superfamily IDs and 1 x incorrect species level IDs and someone adds a correct ID which is from a different superfamily or order then it bumps it back to superfamily. If we disregard mavericks as you describe, then it wouldn’t bump the ID back to superfamily as it does now - until it was seconded by someone else.
I think if this is the only trade off to this aspect of the algorithm though, then the optimal solution lies heavily in favour of change. This use-case is relatively rare and low impact in comparison with what is happening at the moment, which is less logical, far more impacting / a regular occurence.
