Your win probability is exactly the same regardless how many times you’ve lost in a row (assuming the wheel is not rigged).
You can flip a coin and have it come up heads 50 times in a row and the odds of it coming up heads on the 51st flip is still 50%.
Also- why even bother playing the first few units (spins)? If this was such a cant lose system you would stalk the tables waiting for one that has already had like 7 spins without hitting your quadrant.
Then you immediately start betting your 8x unit and you’re already way ahead because you didn’t “pay tuition” on the first 7 losers.
So many holes in his “almost can’t lose” system.
