I do not know that there is an exact answer. Personally, when starting the car for the first time of the day, I let it idle for 30+ seconds to build oil pressure and lubricate all parts. I drive the car below 3000 RPMs, until the oil temps reach 180+ degrees. Probably not necessary, but that is always the way I have treated cars.
With that said, I see that race cars are started and oil pressure is brought up and then they hammer on them. Oil pressure is probably the most important factor. I am sure there is science regarding what you are asking and others will chime in.

I keep the engine below 4,000 rpm until I show about 160 degrees oil temperature. This is personal preference and my guide, for what it is worth, is that when I owned an E46 M3, it actually had a series of lights that went on as the car warmed up and their guidance was to stay below 4,000 until all the lights were on. I remember driving for a number of minutes (8-10 depends on ambient temp) before that occurred.
As an aside, the guidance around start and go is not to let the car idle for any length of time before heading out...............it is important to get the oil sloshing around in the engine................cold start is where the majority of the engine wear occurs and until you start driving.

Regarding race cars.......remember, the majority of them tend to run true dry sump and rely on high volume oil pumps to distribute the oil so sitting still and warming up is not the same as cars that rely on oil splash for lower end lubrication. I used to be with the Olive Garden team in ALMS (550 Maranello). I was in the garage much of the time with the mechanics as they went through their start up and up to temperature routines............

Here is a thread I started two weeks ago that may have some useful information.
