I think both temples are augmented about 1 inch. My corners were brought down close to 2 inches, and my center about 1/2 inch. I was probably a NW4a before. Luckily no thinning on top or in back. Well, now I'm noticing a lot of thinning in the frontal tuff area, though it is still not very noticeable. I'm thinking of putting some RU there.
