I'd recommend you go over to the Predictions section of Lottery Post and note that anyone who posts a sufficient number of predictions sees their winnings regress to the mean, meaning they lose 1/2 their amount bet in a game where the house has a 50% edge. Take a note of how many people are in the Predictions list and then note that a small handful have net gains and each of those persons has a relatively small number of bets that included a substantial prize.
There is a reason for that, there is no system that beats the odds in a game of chance, none. While many make claims to the contrary, their claims are never backed with facts, meaning posting an actual method that can be tested or showing the results of such a test. What generally gets posted by people who promote systems are vague claims using voodoo math. For example, people post pyramids that generate 20+ unique combinations and then the next day tell you how many of those combinations would have been winners across every Pick 3 contest in the US. There are 71 such contests currently reported by Lottery Post. They don't do the math that show what the results would have been if a random selection of 20 unique combinations had been used instead.
A claim of a 65-70% "success rate" is vague. Do you define success as making money or buying a winning ticket on a particular day? Buy enough tickets and you can have whatever success rate you want, but you won't make money. Gamblers suffer from amnesia, they remember their $80 winning Pick-3 ticket, they don't remember the other 166 tickets that were worth $0.
Pyramid systems don't generate winning combinations any more often than chance, and that is a provable fact. I'd be happy to prove it to you. Tell me which pyramid scheme, what state (or states) you want to me to run it against, and I'll show you the results for some period. The same is true of vtrac, short sums, root sums and every other method. They all are provably failures to achieve results better than random chance much less twice as good, which is needed to actually make money.
Not understanding and misunderstanding the application of probabilities is rampant. You won't find any successful poker player who doesn't have an understanding of how to correctly apply probabilities to their game. You will see plenty of people standing around a roulette wheel waiting for some run of red to toss their money on black in the mistaken belief that black is "due" and you'll find no shortage of lottery players who think looking at statistics of picks will give them an edge. It won't, the house edge of 50% is too high and the number of draws is too low even if there were minute flaws in balls or picking methods.
You may not like hearing that but to the extent you think a "system" works as opposed to being something fun to do, you are wrong and not just maybe wrong but provably wrong.
I'm not sure why hearing factual information should keep other LP members from posting, this is a discussion forum and discussing should include fact based information. If you want to post that your new double helix lottery picking system is a lot of fun, have at it. If you want to claim it is a money maker then it is more than reasonable to both discuss that from a mathematical standpoint and put it to the test with verifiable results.
