How Long do you warm up your car?

After I'm done with that I head out the door to see my car idling at a nice 750 RPM with the heat on (warmed up 5-7 minutes) and I drive off.

At the end of the school day I start my car from the other end of hte parking lot (it will reach as long as I can see it even in the distance) and I walk slowly and then I get to the car. I pull away as long as my RPM reaches 1000 or below (average of 5 minutes of warming up)

What do you guys do?

3-4 mins in the summer and 5-6 mins in the winter... your case is approx the same as mine.
