I don't think the HPOP is draining down, because I can crank the engine for 30 seconds with nothing. My understanding is that the HPOP res would fill pretty quickly, even if it was drained down. Also, there's no oil in the valley, etc. I realise it could be draining into the low pressure side of the oil system, but if the pump was working, it would refilll the res while cranking. I can check the levels Saturday morning when I go to start it, although I don't know what it "should" look like.
