SO . . .I think that means that all but a couple inches could drain back into the wings, right? I still have about that in my header, so perhaps that is what happened. In fact, I am puzzled as to why the header don't siphon back to the wings every time you stop. My thought is that the "overflow" line is not "several inches from the bottom of the tank" but in fact up near the top. Draining back thru the pump inlet, if it is close to the bottom of the tank, would require the check valve in the pump to be leaking, right? I am going to "stick measure" mine to see just how much is left in there.
