But are you comparing strategies or tag values? When I think of AOII, I think of a huge number of indexes because that's what the book talks about and that's how most people play it. When I think of KO Preferred, I think of three groups of indexes because that's how it's played. Either could be played differently; but then they wouldn't be AOII and KO. AOII and Canfield Master are two separate strategies in my way of thinking. Even though they have the same tags. Just as HiLo and HiLo Lite are two separate strategies and should be examined separately.
