Anyone ever done a cost-benefit analysis of territory gain?

I am playing as Ireland and through diplomacy am set to inherit Scotland. Additionally, I've annexed Wales and am going to eventually kick England off my isles. Which I have to do if I am to secure Ireland. I also want Iceland, just because I figure it fits in with the two other islands. Sure, a bit far flung but I want to include them anyway.

However Iceland is kinda poor as a province and I know that increasing the size of the empire also increases technology costs, so I'm weary of this move.

What I'm wondering is how much of an increase do you suffer and has anyone ever done a cost-benefit analysis to discover what the cheapest territory you should bother adding to the empire is?

If your relatively wealthy and can add full buildings, including a manufactory to each province then there should be no problems adding as many as you like. If your planning on expanding further or colonizing only take Iceland if you can have it cored early enough to benefit from colonizing range.

So if the land can be improved, then it shouldn't hurt me too much, yes?

Cool. I was worried my successful wars of aggression would yield to a backward state that struggled with technological advancement. Pretty bleak, figured I was wrong but needed a second opinion.

Is there an equation for tech cost based on land?

2.5% extra per province when over eight provinces, according to http://www.paradoxian.org/eu3wiki/Research.

I try not to worry about tech too much and just set some goals for myself. Do you feel it should be part of your empire? Take it! You can usually keep up even if you're big. As long as you don't fight someone who has land tech 18 when you don't, and then 34 if you don't. (Even then, throwing numbers at your enemy can be enough.) Not that most of my games even get to tech 34! Of course, if your goal is to be super tech leader, you may have some more choices to ponder.

Question is : What is better, reasarch wise : Holland or Navarra. Navarra is OPM, holland is TPM, but holland provinces are very wealthy, and bring you considerable tax income, production and support limit. Ussualy i see holland tech little faster than navarra, so i suppose, that holland is better...
