Are those statistics calculated on real tickets you bought, or they calculated on a theorical basis?
It is the theoretical performance of my system. My cash in 2014 ROI was a + 5% of the total profit of the money invested (after paying the fees of 21% of profit) . Two years ago in Spain there were no gains taxes on lottery winnings , so it was much more profitable.
Explain the concepts :
Profit: Gross cash prize you win by hitting a draw.
Benefit : Budget Amount after paying taxes on the prize and then amortizing payment of investment.
How do you get them?
Once I have developed my calculation model, I submit to several performance tests consisting of several modes of play, on samples of 100 drawings (100 random draws, and from the draw 400 to 499 and the last 100 draws). The results of these bursts of evidence, recorded in database tables to check the deviation between what actually came out and what the system predicted.
When I indicate for example that the skill of 5 numbers is 0-6 %, want to express that in the performance tests can give results from 0% (0 sweepstakes) where they got the 5 numbers, up to a maximum (and the best) 6% (6 draws) where the system itself matched all five numbers in the previous test.
Usually the pool of numbers is between 15 and 20 numbers, so then total combinations may vary in each draw.
I don't calculate the statistics of my results.
Measure -> Control -> Management -> Continual Improvement
I have a log of my systems/models with a snapshot (I use subversion) and the %performance and other economics data. I have implemented transversely business processes to monetize the system and methods/protocols scientific to control/improvement; If these steps are not followed is very difficult to have all these matrices testing results on the head !!!
If "Sweepstakes" mean "ready made tickets", then I'm sure that my results are far better than random tickets sold by Euromillions.
I completely agree ! I also bought 10 tickets sweepstakes machine to perform comparisons with my bets . For example , if I make 10 bets EuroMillions (20 € ) , I also do 10 bets ( another 20 € ) automatically by the vending machine. After 100 draws, I have no doubt that applying scientific method has competitive advantage.
I have 3 levels to operate my system, and you can see it en this post (my old username anubina):

5/15 happen 1, or more rarely, 2 times a year. Drawings happen 2 times a week, that's 104 times a year. So, success percentage is closer to 1 or 2%. 6% is huge.
6% is the best case scenario and investment in such systems is highly risky and economically inadvisable (I only gained 5% limpid), so it is a very high risk to only 5%.
Although consistency try to improve profit by not paying rates of 21% (3,000€ prizes lower pay no fees)...
