INQUIRY: G12 versus G15 balance on Comparometer

Mr. PootieCat,

Thank you for your response and the info was very interesting.  However, as per my initial question, I am looking for a calculation of "stop improvement"- not just a generalization that I should go into IR and compare the G15 versus G12.

Thus, is it fair to assume that the G15 is closer to one and a third stops improved from G12 or closer to 2 stops, as per my reasoning in the initial post?
