Start. Allow oil pressure to come up & stable high idle & drive off. This warms the engine & drivetrain up the quickest. The greatest wear takes place while cold & under mixture enrichment.
Do not demand peak power or RPM from the engine until fully warmed up & clearances have normalised.

Once the RPM drop (about 20 sec.) then drive off slowly according to User's Manual. Our's car is equipted with air pump which pump hot air from the exhaust back into the engine during start up to warm up the engine faster.

I let the car run until the high idle drops, then drive conservatively until everything is all warmed up. Then I unleash hell...

The Merc secondary air pump is designed to pump fresh/clean air into your exhaust system. This helps heat up the catalytic converter/s in order to reduce emissions during open loop enriched running conditions from a cold start. It also prolongs O2 sensor & Cat converter life.
Not necessary to wait until high idle stops. In cold ambient conditions this can take a long while.

I'm usually starting in negative temperatures for a good 6 months

One thing I would add is to wait about twice as long for the oil to fully warm up, as the coolant (as indicated by the temp. gauge, obviously), before driving "hard". This advice would, more or less, go for any car, BTW.
