i believe the point is that the there is a pattern to the distribution. we can only safely assume the pattern is on a micro level, but it would suggest there are larger patterns at play.
for instance, is it possible to ship 5 rolls with million dollar winnings to the same store in a week? maybe the answer is yes, but i imagine there's a reason to prevent this. in case it's not clear i am just guessing. i don't really know what i'm talking about.
