when the ASIC boost drama first got publicised by gmaxwells tears of woe
i done some maths on the top 4 pools to see which pools were 'luckier' than others
just done some quick maths

* stats at time of post
hmm
looks like BTCC and F2pool are the ones making more blocks than their hash %
not the other way round
*for those wishing to question the numbers

i have checked other dates and seen no 20% advantage
even today there is only~ +-1% variance of luck
