Yes there was this older lady who did pick 3 and pick 4 a lot with the same numbers. She actually won quite a few times and it was weird because She always had a pattern for each day of the week for what numbers She wanted.
But that PB number alone can fuck things up.
So I know what you mean by patterns and possibly getting stuck sharing the pot. Either way you would still get a shit load of money.
If the lottery allows, always pick numbers above 31. Same odds of winning but less chance of sharing it with people using birthdays as numbers
