.052 Spark Plug Gap

I was reading a few TSB's and I found one that says that the spark plug gap should be increased to .052. Is everyone following that advice, or is there more to it?

Yes, that TSB was unequivocal. Non super charged cars = .052. Results in smoother idle as I recall. I'm about to change my plugs tomorrow too, just finished gapping the irridiums to 0.052 inch.
