What percentage of dealers can throw the ball in a predetermined 5 numbers sector, 30% of the time (and do it constantly)? Dealer of course can train something, but to hit to 5 number sector 30% of time - that is mission inpossible.
I believe the percentage is quite low, below 5%.
And if that will be possible, that dealer will not work in casino....
I fully agree with you on this Bebe. Most experts would agree this is near impossible.
I copy from "Full time gambler" by Holloway:
"I have talked to old-time roulette dealers and pointedly asked them if they can control where the ball drops. Nearly all of the good ones can drop a ball on a specific side of the wheel (ed. note: 19 numbers). The expert ones can drop it within a quarter of the wheel (ed. note: 10 numbers). The good ones are about one in a hundred. The experts are one in a thousand. None claimed to be able to locate a ball in an exact number with but little more than a slight increase over the normal percentage.
Does this this mean you can forget the danger of an expert ball dropper? It does if you are not playing one or two straight-up numbers and nothing else."
In casinos in Europe (at least the ones I am aware of), the dealer starts every new spin from above the last number spun. Give and take a number or two on either side of the last number spun. So there is a known starting marker. If he spins at a speed that he is accustomed to or feels comfortable with, and if no diamonds are hit, then he could probably land the ball in a region that he aims at.
In US casinos the dealer spins the wheel first, and then throws the ball at any time at his discretion.
Considering the wheel spins fast, he cannot possibly pay attention to the number above the beginning of the ball spin. it looks a little "blurry" anyway. His attention is on the players betting and getting prepared to call NMB. I find it hard to hit a planned section of the wheel.
If a dealer lands the ball in the half region of the wheel in every other spin, then it is a normal statistical expectation and not necessarily a planned action. Likewise if he hits a certain quarter once in every 4 spins, that's to be expected as well.
A smart player in European casinos can spot a steady speed, and then count the spaces from the starting point to where the ball landed CW or CCW. Then he can use that info to place bets in the expected landing zone, whenever he senses a familiar ball and wheel speed.
It a great VB system, but requires extreme concentration and lots of practice in identifying ball and wheel speeds.
