Thanks for the reply, but my specific question is does the overage calculated include the CH's from the subsequent/conflicted trip? The way I read 4.BB.5.a it says overage is ACH for the extended trip and SCH for the conflicted trip. And you still get your M/U bank replenished. This seems too good to be true. If it is true then during a conflict you should always take overage and not SUB.
