the duration of warming up depends on the temperatures for me but i believe waiting a little is good for every engine.. in hot summer days a 50-60secs will be enough.. in really cold ukraine winter i do wait 2mins at least.. and in super cold winter days i never turn off the engine when its super hot.. like pushing it for a while before reaching the destination.. i believe its not good also.. driving calmly in last 3-4 mins before i arrive..
if more than 12 hours past i do wait at least rev goes down.. for my current ride i press M button and wait till exhaust flaps open on its own.. then i go.. driving progressively higher revs till oil reaches optimal levels..

below -10c things are not like that cause viscosity changes also.. thicker oil cant reach every part of the engine %100 for a while.. actually cold start behaviors is affecting a lot for engine's lifespan.. not even talking about turbos..
