Stylus Warm-up Time


Do you prefer to warm up your stylus before listening i.e. by playing one side (or 2) of an "expendable" LP?

How long is considered acceptable warm up time?

Do you listen immediately or do you wait until the optimisation period is up?

Also what temperature range do you listen at? (My preference is 21-23 degrees C ambient although it doesn't mean I'll stop listening if it goes to 23.5 ;^)

Does anyone also pray while warming up the cartridge? 
Warming up cartridge would be too much for me, yes the improvement can be audible but I never do such a critical listening unless I am testing something, either different pressings or subtle changes in the system, but I understand those who do.
This is a true audiophile thread.
I have never put vinyl on and thought, "I should listen to this again right now as it might have improved itself." My turntable is next to my gear rack on its own little table and gets ambient heat from my tube power amp, although COME ON MAN...
David99. What heat setting and amount of time do you set your microwave at?

is there a special mechanism to hold the record off the floor of the microwave turnstile giving more even heat distribution?
I tend to listen to vinyl more in the Summer, when I find I need not worry about the cartridge warm up. 

I must say that I find cleaning the cartridge stylus and the record surface and removing static electricity also important. I find 45 rpm rereleases quite good but so short duration as to be a pain. Until I learned that most master tapes were being redone in quad DSD, I was hellbent on digitally capturing my 45s and doing equalization post digitizing. Now I await the quad DSD downloads.

Audiotomb-the LP spins on the microwave turntable of course.
I push the button for the popcorn setting.
