I'm not 100% sure, but..... I don't believe it should be zero, but rather should default to it's 'learned' position to maintain programmed idle... so that when the engine starts, it will be closest to where it 'thinks' it needs to be.... again, not positive, but pretty sure.... let me look at one of my old turbolink or directscan files... think I have a KOEO (key on engine off) log..... I'll get back....
