My understanding is that they couldn't tie an allocation amount to a commercial license in option A and B since sport crabbers could conceivably take a share any where up to all of state allocation of sport and commercial leaving a variable.

Option C on the other hand would have a set harvest target for sports that would leave the commercials a set harvest target sort of.
I see your point though that if like Region 2 goes over allocation that would be deducted from commercial allocation in that region leaving a variable there also.

That would be interesting how they would answer your question.
