Is the adjustment supposed to be done on a hot engine or a cold one?

I have heard it both ways, an MB training instructor said you drive it hot, adjust it hot. In colder climates lot of old timers say to adjust it cold becasue you want it to start up in zero degree weather (with help from the block heater). I do it hot because I drive it before I do a major service....
