A mathematical formula that can guarantee lottery winnings, revisited

It's been almost a decade since I first posted about the scam going around that a mathematical formula can guarantee lottery winnings. Well, I just found out that I was wrong--sort of--and I'm back to make an apology.
Joan Ginther was a math whiz as a kid, graduated at the top of her class at a small Texas high school, and went on to get a PhD in mathematics, with an emphasis on statistics, at Stanford. She then dutifully spend the next sixteen years teaching maths at small colleges in the Western US, but all that changed when she won a $5.4 million share of the Texas Lotto in 1993. Like most lotto millionaires, she quit her job. And like most lotto millionaires, she kept right on buying lottery tickets.
But here is what made Joan Ginther different: she actually HAD found a mathematical formula to guarantee lottery winnings, and she used her initial windfall to keep playing in such a way that she went on to win big two more times in the next 15 years--enough millions to keep up her lotto habit without having to borrow against future payouts. She'd found a way to lower her odds of winning from one in tens of millions down to about one in hundreds--which means that, given the right time and place, buying out her hometown Texas store's supply of lottery tickets produced better than even odds of hitting the jackpot. This she finally did in 2006, winning $10 million from one of a stack of $50 Extreme Payout tickets she'd gotten someone to purchase for her. She also allegedly hired an attorney to come to Texas, pick up the winnings, and return them to her Las Vegas hideout.
Once Texas Lottery officials realized this mega-winner obviously had some formula for buying winning tickets, they launched a full-on investigation of her. This turned out to be quite difficult to do, as she had stopped coming to Texas in person to buy the tickets, so there wasn't much to investigate. They tried to get the FBI involved, but once the FBI learned that she was using publicly available information--published by the Lottery Board itself--and legal proxy buyers, they had to patiently inform the Lotto officials that if researching ticket distributions was legal, and ordering publicly available information was legal, and hiring someone to buy and redeem tickets in your name was legal, then there was no crime to investigate.
Joan Ginther, though, never attempted to sell her forumla. Why would she? It was working fine for her. But after she cashed in for the fourth time, the ensuing investigation resulted in changes to the distribution of tickets that basically rendered her formula useless.
In 2010.
So by the time "Jared" started trying to sell me his mathematical secret to winning the lotto--if "he" had in fact managed to break into the Sanford Archives and get "his" hands on her dissertation from the early seventies (allegedly on the way winning lotto tickets were distributed)--it was already obsolete. So I do apologise for scoffing at the idea that it could be done--but I note that in the decade since I made that claim, every multiple lottery winner has turned out to be relying on fraud and inside access--not a mathematical formula. So yeah, it's not much of a mea culpa, because it doesn't have to be.
I also need to give credit due to Nathaniel Rich and Peter Mucha, the reporters who broke the story. According to Mucha, she never stopped buying Texas Lottery tickets, even after her big win, but the fifth big payout eluded her. As for me, I'm happy to go to my grave at a ripe old age never having purchased a single one.
