I don't know if there is an actual guide for extended nursers like us. I think it's one of those trial and error things for most moms. I'd try just adding 200 cal and see how your milk supply does. If it's not affected at all but you aren't losing weight, then maybe see if it's OK to cut back a little more.
I'm only nursing once at night with my 3 yr old and I'm down to my regular cal range.
