Virtually yes but it will happen. I've seen this concept and have played it some in the past. I don't know what "properly dissected patterns" means. Best to pick a pattern that is less common than others. But it has to be a series of decisions and I'm not sure if betting 12 will suffice.
Forget the 12.
We choose to progressively wager vs the very first 5 hands happened in the past shoe.
Say it was BPPBB
Now we bet PBBPP
Odds to win are 31/32, actually such odds are slightly inferior as a betting sequence dictating to wager more P than B will be less likely to show up.
Notice that if the first target didn't contain any asym hand, on the next shoe our odds are more prone to get more B hands, thus damaging our plan as it involves to bet three P and just two B.
Therefore, one of the theorical best approach is to wait a specific 5 hand pattern involving or not one or more asym hands.
Say our target provided a PPPPP sequence.
Our plan is to bet BBBBB.
But we should know HOW such PPPPP pattern had come out.
From a mathematical point of view, a 10 hand pattern should contain, on average, one asym hand. If such hand didn't come out on the first 5 hands, odds are it'll come out on the next ones.
Split the shoe into multiple 5 hands fragments, that is nearly 14-15 sections (ties included).
Any 5 hand section which previously got one ore more asym hands won't be considered. We want to bet only sections that didn't feature any asym hand.
Even if our real betting action crossed just one asym hand, our overall expectation on B bets will be: 57.93%, 50%, 50%, 50%, 50%. That is 51.586%.
Now we are playing a 51.586%/48.414% game that is better than a 50.68%/49.32% ratio.
Then say that we will be playing just the exact sections not featuring any asym hand for 3-4 or more situations.
Of course we'll lose the sections where sym hands will come out plenty thus favoring the banker but itlr pure 50/50 deviations must include asymmetrical spots.
I mean that if 3-4 or more 5-hand same sections hadn't featured any asym hand, the probability to get the banker advantage is endorsed.
After all, the probability to get 5 P hands in a row in the exact position on the next shoe NO MATTER HOW SUCH HANDS HAD DEVELOPED IN THE PAST and for consecutive times is very very very slim.
Imo at baccarat we shouldn't want to guess a fkng nothing, we just play the probabilities.
