cooperative intelligence

[Dogboy]

Um...couldn't that result in infinite intel?

Say my ally and I both have 2000 points to spend. We both assign 1000 to defense, 500 to coop (targeting each other) and 500 to an attack. My 500 points to my ally becomes 750 because 1/2 his 500 coop goes to my coop. Which means his 500 becomes 500 + 750/2 = 875, so mine becomes 750 + 875/2 and so on...
That sounds crazy. I bet it only applies to attacks, so we each get an attack of 500 + 500 coop = 1000, right? But...then the total is no different than if we never helped each other. I'm missing something here, I fear.
