Like I said, my personal opinion.
The first question is: "Is the draw random?" If yes, then all of these systems that base the predictions on past draws are meaningless. If you've spent hours and hours researching past numbers and sums and vtracs and all that stuff and its meaningless, then that sucks so people get real defensive about it.
If the draw is not random, then that opens up some possibilities. If the numbers are computer generated, then you have to assume that you have the ability to crack the computer code that is generating the numbers. Ask yourself, do you think the computer code would base its numbers on the sums, short sums, odds/evens, all that stuff?
Also, put yourself in the position of the lottery. Your goal is to make a profit. When you are talking non-jackpot games like pick 3/4, what would be the incentive to not make every effort to make the draws truly random? When the draws are truly random, they make about 50% profit. Pretty <snip> good for them.
Right now, I'm not sure anything can improve your odds in pick 3/4. I haven't seen anything that convinces me. I gamble in other ways where I can improve the odds. Blackjack and daily fantasy sports for example. There are clear tangible ways that the odds change or you can add skill to the equation in those.
Overall, the biggest thing I can't get past is why would the lottery not want to be random? Give me a good answer for that question and I might have more of a belief.
