That is a more simple way of putting it
I just wanted to cover the dynamics of what happens as the cards go up and down, above and below the amount of territs.
Hey OP, just FYI, I have never used this information to affect my strategy. I do look closely at what cards I actually have, but I don't think I've ever changed my strategy based on what card I think I'm going to get or what card I think an opponent has. I can see it coming into play on Doodle to some extent, but for every other map, I would say that the benefits of figuring all this out are miniscule compared to all the other components of good strategy.
HOWEVER, I have adjusted my strategy based on which cards I actually have (to stack a territ in a nuke game or choose which territ to take/defend in a flat/esc game).
