BadWolf. You are making the idiot-gamblers mistake of seeing something and thinking the cause is as claimed.
There are not enough data points and just because someone won, doesn't mean there was any plan to it. It just happens that you never hear from the many more similar schmucks with the same plan who happened to lose that week. Newsflash: everyone thinks their ticket is going to win or else why buy it?!
Here's another example to show how you can be fooled. Suppose I write to you with a stock prediction. This stock is going to go up. Just watch.
You check and wow, it went up!
Next week I write to you again this time with a stock that will go down. OMG, it does, exactly as predicted!
I do this 10 times over 10 weeks and have a 100% stock prediction record.
Wouldn't you hand over your life savings so I could invest it for you? You'd be crazy not to ... right?
Oops, sorry, that should have been "you'd be crazy to". Because it's all just random.
How so when you saw the results?
Because you didn't look at the failures. I start off mailing 2^10 people, every week I re-email the half that I was correct on. It doesn't matter if it's stocks or coin-flips, it's flawed logic to work backward from the only successful result.
It's self-selecting because you are only looking at the successes and never the failures and more importantly the cost of the failures.
No different than doubling your bet each time to win all the money back. There just isn't enough money.
