OK, nobody get mad. Floating advantage & shuffle tracking???

Have any of you math types looked at floating advantage as if applies to shuffle tracking? Presumably you would have the advantage in "known-count" slugs where you have a good idea of the marriage (let's, just for the sake of argument, postulate that there could be such a slug), but would you get it in an NRSed slug where you only know the count on half the cards?
