4D Basic
This topic is for the understanding of 4D. There are altogether 10,000 set of 4-D numbers, from 0000 to 9999. If you are viewing 4D as a single entity itself, you will find that all numbers has an equal chance of drawing. In order for an analyst to exploit the statistic possibility of this game, we shouldn’t enclose ourselves within this limitation. We should look at the whole game comprises of readable patterns.
System
Let’s start with a simple concept in analysis. We will categories the numbers into difference system.
ABCD – all digits are different.
AABC – one pair of similar digits
AABB – two pair of similar digits
AAAB – three similar digits
AAAA – all similar digits
System ABCD
There are a total of 210 sets of system numbers. Each system has a permutation of 24 direct numbers. Which made up of 5040 sets of direct numbers, 50.4% of the 10,000 numbers.
System AABC
There are a total of 360 sets of 4D system numbers. Each system has a permutation of 12 direct numbers. Which made up of 4320 sets of direct numbers, 43.2% of the 10,000 numbers.
System AABB
There are a total of 45 sets of 4D system numbers. Each system has a permutation of 6 direct numbers. Which made up of 270 sets of direct numbers, 2.7% of the 10,000 numbers.
System AAAB
There are a total of 90 sets of 4D system numbers. Each system has a permutation of 4 direct numbers. Which made up of 360 sets of direct numbers, 3.6% of the 10,000 numbers.
System AAAA
There are a total of 10 sets of 4D system numbers, 0.1% of the 10,000 numbers.
Each system will have it unique performance when the statistics are probably layout.
How long to hit one 4D number?
In theory, the calculated hit rate for a signle direct number is 23 / 10,000. This works out to be 435 draws to win once. In layman term, it is 2 years 9 months to win once. This will be a fair game if you really able to achieve this winning within the stipulated time but in real life, it is not always the case. Even after 16 years of drawing, there are still numbers did not has a single hit at all, how do you account for such a great differences? Therefore, we can conclude that 4D is not a fair game. You must know the information before you play. Information such as the statistic of season hit, the co relationship of digits and etc. You should play those numbers with a better-hit rate than those seldom hit at all but with the right timing as well.
How can we increase the winning odd?
We should study the numbers in Groups before we zoom down to a certain particular direct number. Imaging if you are playing a poor performance system number, you will definitely see a less frequent hit, not to mention about it direct number.
Numbers in a group will give us the ability to apply certain graphical chart with the data. This will allow us to see the behavious of the group much more clearly. With certain technique, we are able to roughly determine the timing to play the group.
How to Group?
There are too many grouping method to mention all of them here. Below are some of them we can use to study the statistic.
System Pattern - ABCD, AABC, AABB, AAAB
Direct Pattern - ABCD, ABDC, ACBD…etc
Sum Group - Adding all the 4 digits into a sum value.
OE Group - Distinguish each digit into Odd and Even.
BS Group - Distinguish each digit into Big and Small.
NG Group - Study the Next Gap value hit pattern.
Pairing Group - Study the related pair.
Digit Group - Positional Digit Grouping.
