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 ;^)

Harry Weisfield suggests in the manual for my new TT: "a 60 watt light put above a turntable in a cold room will heat up the cartridge just enough to make it much more compliant and track better". "We have found almost all cartridges work and sound best at 72 degrees".
 
Me... I'm old school... I hope that good old fashion listening all day long will work? Actually, all weekend long.
Should (we) start a thread.. "Listening at optimum temperature"?
 
I keep my thermostat at 68 degrees. I guess this means I need to turn in my Audiophile Membership Card.
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.
