Formation Air Patrols deficient behaviour

This is a behaviour present from some itinerations ago, but not sure how to reproduce it, as sometimes is present, and others not.
Playing the Reagan against China scenario I did observe it clearly at last.

Playing Red/China, in the first minutes I shoot down the 3xF-15C3 Formation Patrols of Okinawa, 1xE-3G, and a few 3?xASW aircraft.

The spected behaviour should be the Blue/US AI-controlled side to form new patrols, but as in the attached file saved game, using the cheat mode, no patrols are in the air, and a lot of fighters and ASW aircrafts in Okinawa (of course not 36xF-16C3 fighters, as some were previously shoot-down), and clearly the 2xE-3G remaining.

But I think not ever that's is the outcome, sometimes the IA forms the patrols or the patrols only at the game start and a short while after, many times the second series of patrols and sucessive are not formed.

Someone has detected similar behaviour?
