First, Brian thanks for following up on my post. I didn't feel like getting in a pissing match to defend what I said. So I kind of sat back and let someone else do it. Sorry and thanks.
I think in the end we've offered the poster of the original question a couple of different ways of metering. Metering just the main may indeed be more efficient because you only take the main into account.
Metering after setting the main and fill I believe is more accurate. You don't have to add more light to increase your exposure you just have to add some light. As I've been taught this is one of the fundamental properties of light. It may not matter in some situations but what if that extra .23 stops blows a highlight when you're shooting digital. Then you're screwed. A blown highlight can't be recovered.
In the end, people have to decide for themselves what works best for them but without being armed with the information they can't make that choice.
