Rifle Scopes How many MOA can you get w/ Burris Signature Zee's

[bowslngr]

I ordered a set of 30mm Burris Signature Zee. This ring set comes with .01" offset for both the front and rear ring. If I have done my math correctly, and assuming the rings are about 5" apart, I think that I should be able to pick up about 14-15 MOA by using the offsets. Does that sound right? Unfortunately, I don't think Burris sells the Posi-Align inserts with greater amounts of offset for their 30mm rings.
