I would say twice a day is frequent, but surely many people do much more and I know guys that have admitted that most of the time they never even get the oil up to full temp because all they do is short trips for most of the cars life. I mean I am half way to work (14 mile commute) before my oil temp moves from 160F.

Our local M guru believes that short trips are the death to bearings in all the S54's, S65's, and S85's he replaces them on. He says the car he sees that make it north of 100k are not short trip cars, but cars that get taken out and warmed up. He thinks the 10W-60 just doesn't have time to warm up properly on short trips and that is here in South Texas. But owners also lie so he says it's hard to get accurate info.
