I see that no one really understood " sequence method" and what it does on situable wheels. It's normal, l expected this.
Reason for posting it with examples was to show how very tiny, almost unplayable bias can be detected and explored on the long run. And importance ( correct uplication) of triggers.
What method does is to reduce negative variance in case of " everything goes wrong" situations.
Problem with systems and triggers is that, when upplied on random situations , it produces random results. In non random situations it produces non random results.
It should be obvious from my example that random should be avoided and can not be trusted.
What non random means? It's just that distribution of numbers is not uniform in general due to some phisical reasons.
However this non randomness can take different values . On some values of non randomness " sequence method " will be pointless, flat bet will be more reliable ( player has high edge for example).
So why prng ? To test properly " sequencing method " in relation to system play, need to develop different triggers for different situations. Simple example, if number sector that we target is small (3-5) numbers , bet after hit wouldn't work that good.. instead would be beneficial to look last 5- 12 spins as a qualifier ( besides other things).
To be able to generalise about different situations ( wich triggers serve purpose), need make many tests. To make tests, need data samples wich are not uniform in nature. Remember, we are supposed to be testing situation where player has edge and it's value is defined.
Easiest way to create " test data samples " would be do them manually ( specify how many times each number hits) and then just shuffle numbers. However it's easier to say then to do. Need to shuffle numbers the way wich does represent reality. If it shuffles without accounting for obvious ( no repetition of same number 5 time's on the row.. ets) , test may become not very reliable.
Idea.. to make things random, we could use normal rng to select numbers position in the " list" or " row". And before selecting each number position ,use randomise function of excel... to mix sample.
