Just to clarify:
I'm not talking about betting on the numbers 3, 6 and 9 per se.
Our research is aimed at several number combinations we have identified that involve underlying patterns of 3 or 6 or 9, or even all three.
* various number combinations which are based on number 3
* various number combinations which are based on number 6
* various number combinations which are based on number 9
* how they relate to specific times of appearance, which are also based on 3, 6, 9
Why 3 and 6 and 9? Because they are the specific numbers identified by Tesla.
More than enough work there to keep me from playing on the road for quite a while! Especially as my time and energy is limited by other commitments.
But your query could perhaps open up ideas for others to follow.
I presume that you are not talking about the finals, for example when you say numbers related to 3 you mean 3, 12, 21 and 30 OR 3, 13, 23 and 33, which of these groups??
The first is related numerologicaly while the second group is related according to finals.
My opinion is that since you are following Nicola Tesla clues you are not betting finals.
There could be a number of ways to combine them, for example if we would count them as group and not individually then there would be too many combinations to take under consideration, for example the numbers 4, 11, 23, 25 could be considered as 9 group even are not related directly with any of the 3,6,9 properties.
That's because 4+11+23+25=63 and 6+3=9
If you are combining in such way then all numbers could be related with 3,6,9 properties, but I think you are not doing this because you wouldn't know what to bet since all would fit.
From the other hand, if you consider each number strictly related to properties of 3,6 and 9 groups then you would discard 25 numbers including 0, that's because group 3 is related directly with 3,12,21 and 30, group 6 is directly related with 6,15,24 and 33, group 9 is directly related with numbers 9,18,27 and 36.
Both approaches seem flawed on first sight but for different reasons.
By timing your selection you probably mean to bet only every 3 spins since 3,6,9 are all multiples of 3, yet that doesn't equate necessarily that you will bet every third spin because your criteria don't allow frequent betting.
Please confirm and/or decline where appropriate, thank you.
