This is one of those personal preference things. Everyone develops their own routine.
Mine is fridge, warm, decant, pitch into a finishing starter morning of the brew, then pitch into brew at high krausen normally about 6-8hrs later. Use a stir plate for the production of the yeast from a slant but not for the last finishing starter, if possible I will use wort similar to the brew so I'm not detracting from or adding to the flavors. I have all sorts of wort canned.
