Yep. You did get close to 2x the initial R value though. In 25 years you won't have to worry about that though since it will outgas and you'll be at about R 4 x inch. IMO the only place for massive foam in a house (and it's a very good use of it I might add) is on the exterior of the sheathing, and there you can save a mint by using rigid foam.
