Looking at your sheet swamp, there's a small error on a technicality. The AA pulley is shown as coming with 2 belts when it actually comes with 3. 2 for use with the new crank, and 1 extra belt for the double sided application. I'll try to get an exact measurement tomorrow on my removed stock pulley. I'll post a picture like Andrew did if I can find the time in the evening, using the same style digital caliper.
