Short honest answer: no system changes the expected value. Banker pays with a 1.06% house edge, Player 1.24%, every single hand, no matter how you size bets. Here's the math people skip.
Martingale in one table
Double after each loss until you win. It converts many small wins plus rare catastrophic losses:
Start $10 → after 7 straight losses you must bet $1,280, having already lost $1,270.
7+ streaks against you are not rare: roughly once every ~90 shoes-worth of sequences you'll hit one — and table limits or bankroll end the run exactly then.
Expected value per hand: still −1.06%/−1.24%. Sizing cannot move it.
Why do streak systems feel like they work?
Because they win often and lose rarely-but-hugely. Human memory keeps the many small wins and files the one wipeout as "bad luck". The distribution didn't change — your ruin risk did.
What tracking is honestly for
Room selection & timing — measured, not superstition: which rooms currently show streaky shapes and how often those shapes actually held.
Discipline — signals with published hit rates and sample sizes tell you when there is no meaningful signal. Standing aside is a decision too.
Bankroll honesty — decide loss limits in advance; a tracker cannot beat the edge, and neither can anything else.
