At IMPs:
A lot depends on how aggressively you double in direct seat. With a lot of my partners, something like x/Kxx/QJxxx/KQxx will not act over 3♠, and I find it difficult to construct a layout where you can't make 3NT opposite. Sure, this is a perfect maximum, but it makes game 100%.
At MPs:
how many defensive tricks do we have? There's one spade (maybe two), one heart, one club; if partner's broke then oppo have likely missed game; if he's got pocket change we're beating their partscore, and if he's got enough for 3NT we can probably hold them to 7 tricks or fewer. I would probably bid 3NT at the table, but then I play in a weak field where oppo will set up suits for me.
