Remember that the items are distributed randomly.
There is an interesting illustration (at least I like it): If you let someone write down 200 imaginary coin flips, he will usually avoid having more than ~4 times the same result, so it will end up like HH TTT HHHH T H T H TT HH TTTT HH T and so on. If you let someone really flip 200 coins, the result will usually have groups with up to 7 or 8 flips "length" - everyone would call this totally unlikely to happen, but it is just normal. Same story here on Hfest: Anything can happen. You can get three coeff 6s in two weeks (I think someone did this a few months ago?), you can also get no coeff 5 in two months (look at me, and I am not the only one, as far as I remember). I have 16 BoS, but only seen 4 BoM, ... Never underestimate the surprises that can happen in random distributions
