If the key structure is confusing, you can rearrange it, but don't change the values.
The Key divides the 10 lottery digits into 3 Groups, or Books, or whatever other name you want to give them.
Group A is lottery digits 078, substitute digits 321, which is also stated as 3A, 2A, 1A.
Group B is lottery digits 169, substitute digits 654, which is also stated as 6B, 5B, 4B.
Group C is lottery digits 245, substitute digits 987, which is also stated as 9C, 8C, 7C
Lottery digit 3 is Substitute digit '0', which is stated as OR (zero R),
The 'R' is part of Group C, but can stand alone in some circumstances. This requires further explanation but this is not the time for that.
To answer your question about the Key.
Any arrangement is acceptable so long as there are no repeats.
A lottery digit and substiture digit should never be the same.
There are three As, three Bs, three Cs and one R.
These values are permanent assignments and must not ever be changed. If they are, then all data
logged with the original key must be set aside.
The purpose of the key is to create the means to establish a Base Foundation having all the information needed
for tracking purposes.
Bottom line, you have to create the base foundation in the manner i've described.
The key also separates the lottery digits from the workout.
There is a procedure for maintaining an inventory, but the data has no practical use, except for playing lottery digit doubles,
which is a separate topic.
No attempt is made to classify the substitutes as hot and cold, odd or even, roots, sums, etc etc.
The lottery substitute digits are OBJECTS having no quantitative value whatever.
The means by which the lottery digits are generated by the lottery is unimportant.
Doesn't matter if ball machines or computers are used.
The lottery digits can be seen as simple triggers.
