My wife thinks I am nuts!

The time it takes mine to drop off the fast idle varies quite widely, anywhere from about 10 seconds to nearly a minute. It seems to be partly but not entirely temperature-dependent, and I'm talking about fully cooled-down starts here as in overnight or after 10+ hours at the office. If it matters, I have the FRPP cold air kit and tune.

I can agree with waiting for the RPM's to drop. I refuse to believe any car takes 5 minutes for that to happen. Those who wait beyond rpm's reaching idle are wasting their time.

Start the car, put you seat belt on, check your mirror adjustment and slowly drive off. Don't go WOT for a little while.
It's really that simple. If it's really cold, wait a bit longer.
In the old days with a carburator on cold mornings, I had to wait until the automatic choke dropped from high idle. If I didn't, the car would stumble because the automatic choke would close too quickly when you touched the gas pedal.
This isn't a problem with fuel injected cars which atomize the fuel better and control the fuel air mixture by sensor input rather than closing too quickly like the mechanical automatic chokes did.
Driving a car at light load is easier on the car than idling. At idle speeds, your mechanically driven oil pump is spinning slow, at higher speeds it spins faster and pumps a greater flow rate of oil. Oil pressure is a function of viscosity and flow rate.
