"No-Mid-Shoe Entry" secret language makes no intelligence at all for the player. The order of the cards is not consecrated. They got that way by being blindly shuffled, then cut at a random end by one of the players. When things are going great, there's absolutely no propensity for them to keep going great. If somebody jumps into the game mid-shoe, all it amounts to is a modest blinder shuffling.
The only two things that matter in blackjack are to engage in recreation of your hands right, and to raise your bet when the shoe favors the player. The only time the shoe favors the player is when there are more high cards left. If you can become skilled at a method that recognizes those times, then you'll be raising your bet according to something that matters. Everything else is a fritter away of money and effort.
