You forgot RC7, but I would really round up anything above .5 and round down below .4. But then again, AP in blackjack is all about consistency, as some people round, truncate, or floor their TC. So just pick how you come to whole number and don't change how you come to your answer. BUT! I would really suggest rounding for VIP. Also, hi opt 2 takes a lot of concentration, <read> it makes you look like a card counter, unless you have really practiced it for thousands of hours and you're truly a pro. plus adding VIP wouldn't help you're cover. I haven't made the leap yet, still using hi opt1 with VIP. It's pretty easy, 1.5xRC. I can hold conversations and still keep track of the cards.
