Variance:
Calculate the variance by dividing the sum of squared differences by the number of observations (7): \text{Variance} = \frac{164.5669}{7} \approx 23.5096Variance=
7
164.5669
≈23.5096 (rounded to four decimal places).
Standard Deviation:
Finally, find the standard deviation by taking the square root of the variance: \text{Standard Deviation} \approx \sqrt{23.5096} \approx 4.8485Standard Deviation≈
23.5096
≈4.8485 (rounded to four decimal places).
So, the standard deviation across the best 7 numbers is approximately 4.8485.
Still you must look in advance - in front, so calculate only for predicted place. If will look all overal and will select best - then will have maybe every time 3 STD, but such not be when will start play in casino for money…
That is this chart only counted in groups of 9 pockets.
And here is all recalculated acordingly mine methodic if to count direct we will get in pick 3.1 STD if i good remember.
With this data all will be good if not holes near to positive area in 5-8 zone and 27-29.
here are few moments - we do mistakes when colect data and second is that i can change only few distances to theese holes and all will be other. Enough to remove 3 distances from central place to theese holes and we see different picture. So this i try to recalculate - what can be and get what i get and that is usually very exact, so after such recalculations left only 1STD what is not enough for me, I play from something near to 2STD recalculated…
