I know logging it as both PIC and dual recieved is LEGAL, that wasn't what I was saying. Way back when the way it was explained to me was that you didn't do yourself any favors logging both PIC and dual recieved for training flights because some places split it up anyway (apparently Mesa? and I can't believe I forgot about airlineapps. It was a pain getting my times to add up with some flights logged as both PIC and dual). And as I started instructing I followed that pattern and have been doing it that way for 2+ years now. Have I done my students a diservice? I don't think so.
