I may not be understanding you right on this Doug, so if I am excuse me for asking, but are you confusing deliverance with the "casting out of Satan himself thus making one perfect", by your beliefs on this?
Deliverance is not casting out Satan, but more like casting out his "offspring" or fruit of him that were formed from the union of him with the soul of men, such as lust, hate, greed, bitterness, jealousy, ect.
And as I said before the LORD instructs as to what is there, and IF it is to be removed at that point in time. Discernment MUST bow the knee to His perfect will, else the last state of that person is worse than before. Just because something is discerned, does NOT mean He wants it removed at that moment in time, because they may not be strong enough in Him to withstand the onslaught of the enemy trying to get back in.
As an example of this and how I learned the principle, once I was praying for an elder in a church. It was about an hour of the Lord pinpointing things to remove, and included an instantaneous healing of the man in one area.
When I got to the end, the Lord showed me a spirit of nicotine in the man's lungs (sorry smokers). Now I personally did not know the man, had no idea if he smoked or not. But just as I was going to open my mouth to command it out, the Lord spoke, "NO!" I was startled, because up to that point He had never shown me anything He DIDN'T want removed in the next 15 seconds.
So I asked Him why??? He said, "Tell him I have delivered him of this twice already, and twice he has taken it back. Tell him this time, he'll have to pray and fast to be delivered of it." (Being shown something like this is the gift of word of knowledge, for those of you who have never seen it in operation).
So I told the man, and he said that was true, adding, "Did He tell you how long I have to fast?"
So the point is, it's a PROCESS that continues until the 3rd day of perfection, as He said to Herod. We decrease, so that He can increase in us. Blessings....
