Uh, your own results prove that the 13th falls on Friday more often than on other days of the week. Yes, the numbers are "basically" the same, but no one has been arguing that there's a big difference, have they? No one has claimed that the 13th is a Friday 25% more often than a Monday, or anything like that. Next time the Lakers beat the Bullets 104-103 or something, are you going to say that they should score it as a tie in the standings, because the two teams got basically the same number of points? :-) :-) :-) -- Adam [snip] >And finally, here are the results of the run: > >Summary of days which the 13th happen on: > > 4800 total items > > Sun found 687 times > Mon found 685 times > Tue found 685 times > Wed found 687 times > Thu found 684 times > Fri found 688 times > Sat found 684 times > error found 0 times
