+1 bazillion. You start the car, let it run for a couple seconds; then start driving like you said low RPM off boost.
Less time with engine up to temp = more time wearing components not up to spec clearances from the temp. About the worst thing you can do for an engine (other than running as hard as possible) is letting an engine sit and idle.
