No, I don't have a positive advantage over blackjack. I can only go by the results, which is more money in my bankroll then I started 2.5 years ago playing this way. Understand the mathematics behind counting systems to reach a 1-2% advantage with no mistakes, now I will observe big or little cards coming out if I'm stuck on a decision. I do agree playing thousands or hundreds of thousands of hands will get you ahead of the game as well, but my time in my business is much more valuable. Occasional play , short duration, with big bets, this is the way to go!!
