(Not your first rodeo so sorry if redundant) over the years I get a sense that the growing volume has implied more batching of production and shipping, fan-out of delivery processes to local centers (and thus lack of strict queuing), and other forms of parallelism. And maybe the 7s orders in the wing were batched with new orders. At this stage IMO it is give or take a couple of weeks, which seems to me acceptable “noise” for the complex process; even if the starter “signal” intent is to do it following strict order heuristics.
