As I said, ther may be some models with a pan configuration that would keep a little in the bottom even with the plug out. I've seen the inside of a 123 pan and know that this could not be true with that model.
Also as I said, I'm not against the topsider, the main thing is that you use it again after the oil has had a whil to make it down, don't do a ten minute suck after the engine is cold. You're leaving too much clinging to everything.
