I think the logic about warming up (not that I agree with it) is that you don't want to put the engine under load until the oil has warmed up enough to get everywhere it needs to be. Of course, if you don't put the engine under load, it's not going to warm up as fast...

I personally, start off before I start my engine--that's the nice part about my house being higher than the road...and using 2 oil pan heaters--just put it in neutral and coast off until the first stop sign where I bump start.
