It works well in games that are tightish but very aggressive. Meaning 2-3 to the flop for 2-3 bets. This gets you "isolated" by worse hands - hands that would've folded had you raised. It has to be balanced, of course, but it's a very valid strategy.

This is the sort of game i'm talking about. Cleary if you know you'll get called by KJ and AT anyway, you may as well raise. What sort of frequence do you think is best with say AKo. Limping 20% of the time? 50%? I really have no idea.

I like to do this in SH games for the same reasons Clarkmeister outlined.. I'd say rather than a percentage, just do it in good spots. First off I'd rarely make this play with AJ.. and less with AQ than AK. That's because these hands are Seriously downgraded with multiple opponents, whereas AK is less so. Especially if they're offsuit.
Asside from that, if I've been raising a lot lately with lesser hands (steal or isolation attempts usually), then I'll go ahead and raise. Otherwise, I may limp, as long as it doesn't look like the field will be too large.
Of course, if it's a tight game but there's one loose player who will pay off, always raise.

One more point - although it's certainly a valid play, I don't believe it should be the standard. No more than 30-40% IMO. That's plenty to disguise your hands - beyond that you're just giving up value.
