Just of the top of my head, it seems to me . . .

Except a situation where the counts encountered are forced to be disproportionately on the high positive side, no?

An unbalanced count performs better the more the counts are near it's pivot. UBZII is near a hi-lo +2, KO near a hi-lo +4.

In strict back-counting, a disproportionate number of higher-bet counts would favor KO's better accuracy at hi-lo +3, +4, and beyond. Conversely, KO's poorer performance at negative counts ( and UBZII's better) are ruled out of the equation.

Further, if you are only going to be playing positive counts, then the indices used for unbalanced counts in RC-mode could be recomputed to reflect the decks-left composition of wong situations.
