I have also used Gail Howard's system and won. Not the jackpot...yet. But I can tell you this: When I use her systems I nearly ALWAYS win SOMETHING and when I don't I win nothing.
Basically Gail's system does exactly what she says. It reduces the odds of the game in your favor.
I've won hundreds of dollars using her system and know that if I just keep playing and adjusting and improving my skill at using the system to pick my numbers I will win.
I recently used her system to pick 5 of the 5 winning numbers in the Fantasy 5 game and WON 4 out of 5.
In the past I've used her system to win 4 of 6 in Lotto and consistenly win 3 - 4 of 6 in lotto using her system.
She says in her book that Fantasy 5 is the best game to play as it has the best odds. This is true. So I recently switched from playing lotto to playing fantasy 5 and after only a few tries won 4 of 5.
So I know now that I can use her system to finance my playing and not have to use my own money.
The problem I have now is getting some software to print my tickets as all tests indicate that I'll have to play possibly 50 or more entries to win the jackpot. That's alot of scribbling!
Anyway, that's my 2 cents.
Buy her software & books. Read it & use it. It works.
