Your assumption is flawed. Production rate does
not equal delivery rate over the short term. The production rate is reasonably constant month to month, for what should be obvious reasons. Delivery rate varies dramatically month to month for a variety of reasons. A major reason is that operators tend to want to take delivery at certain times of year - such as right before the big summer season, and not want to take delivery in the middle of the winter when traffic is slow (their own version of 'just in time' supply). Since it's not feasible to produce 8 aircraft one month, and 20 the next, they do what's known as 'build ahead' - the aircraft are tested and prepped for delivery, then parked for a month or more until the operator is ready to take delivery.
