My goal with every system was always to end up with one single pick as a "best guess". This was, and remains the driving force,  because it creates a minimal budget.

Not that there haven't been coincidental hits, but they are too few and far between to be profitable.

Systems that result in groups of numbers to play per draw are prohibitively expensive, and when they fail to produce a hit in a reasonable time frame, can render a single win as not profitable because of having to cover the expense of the losers... play 1 number on the pick 3 for a week, cost $7... on a hit of $500, profit is $493. Play 10 numbers for a week, cost is $70 and profit drops to $430. Covering just 10% of the numbers, 100 plays per game in a week costs $700, a single win is still a $200 loss. Then there is the logistics of having to print out 700 tickets over a week.

More combinations per game is definitely not the ideal solution. Since some states have 2 or 4 pick 3 draws per day, you can see how this would escalate quickly.

So I have always tried (and mostly failed) to generate that 1 pick. Since I could not even figure out that one pick on a pick 2 with any consistency, I have reduced my $14/week budget down to $12 by only playing one Power Ball ticket (with opt in multiplier and double draw) per draw. I still use my app and alternate between picking from the Follower Markov Chain or from the classifier output, but that is where I ended up... it is boring waiting for that dumb luck coincidence, but it stays on a budget, so if there is a coincidental win, it is the cheapest way I could have obtained it. It is still a $624 per year budget, which means at the usual power play multiplier of 2, it would take 4 hits of 3+1 or 4+0 to cancel the expense (or 2 hits of 3+1 or 4+0 on the second draw where they pay a flat $500)

So far I have not done better than 2+1. The usual outcome being 0+0 to 2+0. I do not have any new alternatives to number selection at the moment.

Not ready to say chasing this hobby was a complete waste of time yet... but it is certainly leaning in that direction.
