It was RJ that mentioned "consistent profit"; I only mentioned consistently matching two or three numbers with enough four number matches to show a small profit. At best I only proved it's possible to consistently get four number matches on one pay line playing a 3 if 4 abbreviated wheel. I know the odds so I know it was probable the next four times I matched four numbers using the same wheel, it was possible to not get any four number matches on a pay line.
I quit that playing strategy because my object was to win the $100,000 plus jackpot and that can't be done by only matching four numbers. It's possible I could have played for an entire year off the winnings with little or no profit or maintained the 50% average and won $1 for every $2 I bet. While winning $3120 a year by betting $20 a day six days a week might sound like a good idea on paper, it means updating the chart every day, getting the 14 numbers to play, putting them into the wheel, accurately filling out four playslips, and taking them to a lottery retailer. After seven weeks, I decide it wasn't worth the time and I'm not tauting it as a winning system.
"no one makes a consistent profit playing the lottery"
A couple of weeks ago I was looking for something on the KY Lottery website and stumbled into the "Winners" section where they show players holding over sized checks. In the Pick-3 section one player's picture was shown 12 times winning various amounts from $1400 to $8000 in less than two years of play (20 months). The guy had winnings of $31,950 playing the Pick-3. His first three wins of $4000, $4000, and $3500 were in one week and his fourth was for $8000 was a few months later. His next 8 wins were from January 2012 and from the amounts he won, it looks like he was playing $2 to $2.50 straight/box tickets for those wins.
I don't know how much he bet a drawing or why he decided to cash his tickets at the lottery headquarters (maybe he likes having his picture taken) so while it doesn't prove he consistently shows a profit, it does shows consistency in winning. He could show just a 50% profit with an average bet of $14 every Midday and Evening drawing.
