Get a digital kitchen/cooking thermometer. They go from like -32 to 270 degrees and they can help you cook a wonderful medium rare prime rib roast. Oh so yummy! Overcooked meat is a problem destroying the world these days.

From room temp to 90-100 I would guess around 30-45 minutes and from refrigerator to 90-100 in about 45- 60 maybe 70 minutes. It's not hard to learn and if you need the entire 2 weeks to perfect it, maybe you should just give up now! Frozen in about 90-120 minutes but I don't recommend that especially where you are hiding it.
