Ok, then, you asked for it!
I mentioned starting with just three pounds of extract at the beginning. I'd add the rest of the extract at flame out, as to not screw up the hopping schedule. You can add it with 15 minutes left in the boil, though, before the flavor hops start. It'll stop the boil briefly, but you can start timing again once it comes to a boil. Since it's a LOT of extract (what? 9 more pounds?) adding it at the end makes more sense to me, as it'll take up a LOT of room in your pot! As a general rule, the more volume you can boil, the better the beer. A 4 gallon boil is preferable to a 1.5 gallon boil, for example. If you can boil 3 gallons and no more, then I'd definitely add the majority of the extract at the end of the boil.
