Sometimes the way to go, regarding an AEA rule, is to state what you want to do, and then work through the rule book and see if what you want to do snags on anything. As opposed to reading the rules for what YOU CAN do.
It's a little different with the codes, as they are such a specific set of rules, it's often easier to "forget" about other contract and codes, and start fresh.
But, the code does say "(E) Rehearsals for any member shall not exceed eight (
hours per day, and combined weekly rehearsal and performance hours shall not exceed thirty-six (36)
hours per week."
Now, if the code was subject to overtime, then you could schedule the 10/12 and just pay overtime - sadly, or rightfully so, depending on how you look at it, the 99-Seat Plan does not have any stipulation for overtime.
