I hear and read people trying to test strategies.
They even buy programs to do it.
I'm not sure how they try to test roulette strategies and I'm sure each one does it differently.
Some use excel, some rx, some the free online applications.
And I guess they can use different numbers of spins. Some may test with pen and paper for a few hundred spins, some other may test a few thousand spins, some test millions of spins and some may even test billions.
I believe testing a system is a very delicate thing. A very difficult thing. And it is most often done wrong. That's why, although we have posted a very detailed article about system testing
, I believe it is much more important to deeply understand a strategy than test it. Understanding doesn't mean just knowing the rules, but identify the main concept, the weaknesses and strengths, and the kind of sequences that can make you or break you.
As to those who believe that if they run a system for millions of spins is a good test of its effectiveness, I want to say this:
There is no point in testing millions of spins. It can tell you nothing about the system. It only tells you about the house edge.
It is like trying to test your health by asking if you will be alive in 300 years. This can tell you nothing about your health. It only tells you you are mortal.
