Guess we're just going to differ a bit on this.
I agree that the table status (loose/tight) plays into it, but that doens't come along all of a sudden. It starts from early on and normalizes as you find where the table/players are at and what the raise thresholds are. It isn't simply raise 4xBB this hand, 7xBB the next hand, and 5xBB the next hand, etc continuously. It's more of an iterative process like 3xBB to start and evaluate who calls how much. Then maybe adjust it up to 5xBB and evaluate to see the change.
But once you've found the balance point (let's say it happens to be 5xBB this time), then your standard opening raise would be 5xBB and standard raise with limpers would be 5xBB + 1xBB per limper. On average (I'd venture 90% or more of the time), I wouldn't sway from this. On the rare occassion that I have some mega-LAG with a VP$IP of 80% or more, then I might push a bit more with a monster figuring he'll come along. But even then, I have a better chance of getting mega-LAG's money in my stack if I don't play too far out of the norm all of a sudden.
Of course, like I said before, while this does apply to some degree at the micro limits and the any two card mentality, the BB #s could be much higher. At 2NL, a 7-8xBB open raise is not uncommon, but just because folks are looser and playing anything, doesn't mean you have to be all over the board. So in my opinion, 2NL is easily beatable without developing bad habits of predictability/readability in bet sizing.
