If I have a full hookup site I will hook up my black tank flush and flush for a couple minutes every trip. If I am at the dump station and there isn't a backup, I will flush for a couple minutes as well. I'm probably doing it excessively, but its worked for me.
I usually keep the black tank flush on while dumping the black tank to help move along the solids, then I'll close the black tank for 2 or 3 minutes to build up the water level in the tank, then open the black tank again. That "surge" of water coming out helps to clean up most of the solids. Then I make sure to leave a couple gallons in the tank after I close the black valve again.
I do the same thing as you. If there is a line at the dump station I will just dump then flush back at my storage lot.
