But then again, you might be onto something ..... if you look at the numbers from your assertion, they tell us:
142 Blocks where the Pool Scoring Hash Rate was below 10 Ph/s
23 Blocks where the Pool Scoring Hash Rate was above 10 Ph/s
Statistics and numbers can always be used or misused to prove or disprove a point, so here are some more numbers for you...
In December, 107 blocks were found above 10PH and only 55 found whilst below 10PH, which is a little different to the 142:23 ratio claimed in the posts above.
