In the end all that matters is the future and you are being misled by the fact that this "system" has won you money this year. If a standard die came up "3" 7 times in a row, would you believe that this is evidence that a "3" is now more likely? No, you wouldn't because you know that all 6 outcomes are just as likely. You are taking a statistical anomaly over a small sample size and asserting that it is somehow proof that this is a winning "system".
I just think other readers should think critically of this "system"
Two independent events between two independent teams under independent conditions in different stadiums on different nights = zero correlation. That is a fact.
Anyways, I'm done. But please don't blow smoke where there's no fire.
