If you have some knowledge and follow this thread you could notice how we moving towards visual prediction methods.
Traditional roulette visual prediction
Based on everything previously explained about tilted wheels, we understand that if we enter every spin when the remaining time of the ball’s travel is approximately constant, the outcome of where the ball will drop depends solely on the rotor speed, or more precisely, the rotor movement until the ball completes its remaining rotations. Assuming that the ball will hit the same diamond (DD) for every spin, it also means that after the ball passes our DD at a particular time during the spin, the ball will make a fixed amount of whole rotations until it drops. This understanding can be crucial for predicting the outcome accurately.
We already learned why we can’t deduct ball rotations from the start of the spin. It doesn’t help us to have same amount of ball rotations from end of the spin.
If for example we want to predict in 6th rotation from the end when remaining time of ball traveling is about 10 sec, if the spin is 20 rotations long we can’t just deduct first 14 rotations.
If next spin is 17 rotations long and we deduct 14 ball rotations, we will have prediction in third rotation which will give us completely different result not related to previous one.
Therefore we need to use something else.
All visual ballistic concept is based on how to identify particular ball rotation from the end of spin, so after that rotation we can have constant ball travelling time until it drops.
For example, if we want to detect when the spin ball is 6 rotations to the end how can we do it?
The simplest way is to observe spins and to estimate it. After some practising we will be close with results and estimation. We can stand next to the wheel observe it then in one moment read number at our DD, then count remaining rotations that ball makes. If after each attempt we get six remaining rotations we do it well. But can we really do it on so easy way. The answer is hardly. Sometimes after estimation the ball will make 5 rotations sometimes 6 sometimes 7, most likely we will be in that range.
This is what Jafco encourages in his ebook, advertising it as a revolutionary way of prediction.
He made nice videos for training where on his wheel is possible reasonably well to guess particular ball rotation 3 or 4 rotations before then the ball drops. At that wheel ball slows down extremely fast about 300-400ms per rotation therefore it is easier. On real casino wheels it is more 130-200ms per rotation which makes it harder. To highlight it, ~200ms difference is the best that we would get at the best time moment during the spin, predicting 3-4 rotations before ball drop may be only 100ms difference which on 1.6s long ball rotation is not much. For example it’s much easier to spot difference in between 1000 and 1350 ms per rotation, compared to 1000 and 1150ms on wheels in good condition.
Personally I believe 3-4 rotations before then ball drops is too late , just estimating is not good enough also there is a bigger reason which will be explained soon. Considering that he uses electronics timer to clock rotor but doesn’t use it to find particular ball rotation really is not justified. However most people who bought his system with previous knowledge close to zero are happy, everyone has to start somewhere.
There is some discussion about Jafco’s system here
Jafcos ebook explains reasonably well principles of tilted wheel prediction but it doesn’t have solution how to define particular ball rotation during the spin, except estimating it.
Yesterday I looked his ebook again just to make sure i do nto make mistake.
I was searching if there is anything explained about ball deceleration knee point during ball spinning.
I did not find anything so I will explain it here because it is important for a VB player who by estimation is targeting particular ball revolution.
Better way of estimation is if we target particular ball revolution where time difference in between two rotations is greatest.
It’s easier to detect it, since at that moment ball rapidly deccelerates.
In roulette world this is called the knee point. The knee point on some wheels may be strong, it can happened in two ways that in particular ball rotation the ball decelerates rapidly, or perhaps right after the ball deceleration rapidly drops. It is never 100 % accurate but in some cases it may be accurate enough to produce an advantage and definitely it is a better way to predict. Such point in usual is when the ball is about 1-1.3 seconds per rotation (or 5-6 rotations before then the ball drops), that gives to the player possibility to predict earlier. When prediction is earlier even if particular ball rotation is missed error created is smaller since time of rotation is shorter. The knee point can be noticed when player looks for sudden change in ball speed, if he can hear the ball sound it also may help.
Picture above shows times of ball rotations.
Data is taken from roulette computer, after 17 ball rotations were clocked and processed.
As you can see on the chart first ball rotation is about 500ms then with each next rotation time increases. Important here is to notice point marked with red arrow. You can see that next rotation after that point decelerated more, therefore time of that rotation is increased by more than what was happening with previous rotations.
Also notice how deceleration is dropping 3-4 rotations before the end. That is why on most casinos wheel is not recommended to predict 3-4 rotations before ball drops. At that stage of roulette spin ball is leaving vertical edge of the wheel, it may even drop by let’s say 1 mm, friction is smaller but and radius is slightly decreased, drop in ball deceleration is much higher then you may expect or as an average Joe can spot from this graph.
This orange graph shows how ball decelerates per ball rotation.
Differences in milliseconds of one ball rotation compared to previous one.
Red arrows clearly can show the knee point, you can see that previously differences in between ball rotations were 50 to 100 ms and then suddenly we get 250ms.
Finally this green graph shows real ball deceleration not per rotation but per second.
We know that rotations on the end of spins are getting longer so we are comparing longer times therefore previous graphs will show greater differences.
This graph is real representation what is happening with ball in time.
We can more clearly see the knee point but more importantly as red arrow is showing, we can see how ball deceleration is rapidly dropping towards the end of spin. This explains why predictions by estimating particular ball rotation shouldn’t be done 3-4 rotations before ball drops on casino wheels.
And again same question, can someone understanding all of this finally make any profit in casino?
I would say yes.
Now, the time from prediction to the end of spin is not 15-20 sec long that can deviate but shorter and reasonably constant.
Until now the player knows that he needs to time the rotor and make appropriate adjustments, if he is skilled to estimate let’s say 6th ball rotation most of the time, if the wheel has reasonable tilt, if ball jumps distribution is not close to random sure he can. Better conditions better his chances are.
But there is more..
