Ok, here's my proof:
Monday: http://lottodrawodds.com/wins/140929.jpg
Just polished off a working copy of my system. I had a couple of 20s left in my wallet from my scratch off money and $3.25 in my online account. So I'm the set with the best odds of hitting first, #1 in the list. Since it was my first time playing and I was down to very little play money left, I played boxed in the store and a quarter play online. Of course, it hit straight.
Tuesday: http://lottodrawodds.com/wins/140930.jpg
I decide to throw more numbers/money at it and hopefully win more often. Of course, nothing hit. :(
Wednesday: Group #2 on my list hit (I wasn't playing #1 because it had just hit recently and the odds of it going again so soon are NOT good)... I had just played them Tuesday. While my system did give me the right numbers to play, I didn't play them so technically I didn't win here. Here's why I started this post. I changed the numbers I played because of personal bias. The number 7 had hit so much recently, I thought it couldn't possibly hit again. So I didn't play a set with a seven in it. That cost me $500.
Thursday: I decide to start playing #1 in my list in the store and #1 and #2 online. Nothing hits.
Friday: http://lottodrawodds.com/wins/141003.jpg
Really, really wanted to make an educated guess and chose my sets. But, I didn't want a repeat of Wednesday... played #1 in store, and #1/#2 online. #1 hit, straight, $1,400 win altogether.
Here's the in store wins: http://lottodrawodds.com/wins/store.jpg
In summary, I've spent around $100 (I think) and I've made $1,690. I'm going to guess that this week's lucky is better than average. But, just based on in-store cost/wins. I'll spend $600 and if I hit just twice, I'll make $1000. Leaving a $400 profit. Online is even better because the payout is more.
