Well, maybe you can
I do.
Well, kind of.
What I've done is adapted UBZII for different numbers of decks, using the same concepts as KO. That way all I need to remember is the IRC, KC and Pivot and away I go.
It is a bit of a fudge though.
I've tested my theory extensively using CVData2 and the results are superior to the UBZII composite indices.
But be warned, a level 2 count is quite a bit more work than KO's level 1.
The results are superior to KO. Is it worth the effort? Only you can decide that.
It was for me, but then, I came from AOII (too hard) to KO (too easy) and finally UBZII (a happy medium).
