No clue on jackpots but I have seen a few sets while I have been here that have seen pools of numbers that have had all the winning numbers in them in them.
BTW wording your post that way is gonna piss alot of people off. Just because you don't believe a statistic or piece of data is important, doesn't mean that it isn't relative to someone else's strategy or method of playing the lotto. I don't know if you realized it, but the way you worded your post, it has basically insulted anyone who has posted on this site.
This is a lotto site, where people discuss ideas and theories, and strategies. As for people having nice picks, good for them. I don't think they are posting to be what you have termed the coolest picker of the week. They wanna win the jackpot like everyone else and if they have nice picks that week they should be congratulated. Seems to me your looking for a magic bullet theory to winning the lotto, which you will not find. No one bats a thousand in baseball, if they are hitting 300 they are considered to be doing very good. In this forum your looking for new ideas to try, or strategies that will help you in your number selection. That with a little luck on how you populate your wheel and you may have a shot at the Magic combination of numbers that will give you the gift of financial freedom and time. People here want to reduce the odds by wheeling and using strategies. If your not here for that, your gonna be depending on dumb luck if you are not using a system.
