They are called "something-mumble opportunity" I think (yeah, I know, that doesnt help much).

I never got these positive-only two oturn comps till 23 or 24 and higher. They seem to take the first action you select when it pops up (turn one) and then boost that effect on turn two. Nice, but not much of a make or break thing. I find the five turn positive comps to be more helpful when trying to squeak out something.

Then again, I am lousy at crafting, your mileage may vary.
