That is not entirely true. Even John said there was a separate checkout for index plays, there was also a slight deviation to the basic strategy chart for the BP because he only played positive shoes, what would you call that. Also remember the time line, by the time the mid 90's rolled around John wasn't actually playing anymore for the MIT team, and soon after it was Mike managing the team. They used indice plays whether you want to believe it or not. As for KO, its a fine way of counting if you play alone or recreational, but there are no professional teams or players that use KO full time. As for converting the true count, if you are struggling to keep the count while you estimate and convert, then you probably aren't as good as you think you are. Its all easy once you practice enough, its just that KO is easier quicker, big deal, if you want to stop there fine. Riding a tricycle is easier than riding a bicycle, but once you learn how to ride a bicycle its more fun and just as easy, and I doubt you'll be going back to the tricycle.
