New Club, there is something you haven't thought of.
If some group does this, it will reach the media. Then there will be other clubs that form.
When 2 or 3 such groups start covering all the numbers, then suddenly the pot has to be split 3,4, maybe even 5 times, (2 winners and up to 3 pots).
At this point you are not breaking even or even coming close.
Now if you assume that yours is the only group doing this, you also have to assume that no one screws up. Or that at every gas station buyers go to, that the clerk will allow them to stand their for 30+ minutes handing over form after form. Also you have to assume that no form is lost, or mismarked, no mistakes at all.
What is the chance of that with over 146 million tickets being purchased?
In the end pools don't make sense.
If I buy 1 ticket, my chances are basically zero. If I buy 10, then suddenly my chances are less than 1 in 14.6 million, or in other words zero. If I buy 1000 tickets my chances are still so ing low they may as well be zero.
A pool where 100 people buy 10 tickets each has the same chances as 1 guy buying 1000 tickets, which is basically zero. The difference is that if the impossibly improbable happens and the single guy wins, he gets all the money. If the pool wins, then everyone is better off, but no one is set for life.
Since you are going to lose in a pool almost certainly, unless you organize such a group as described here,(which would most likely require more people, perhaps 1.46+ million at $100 each, but then who cares about doubling $100, best case scenario), you should just buy your own tickets.
