my 2c is that when kano had 45 Ph, having a good site might have moved him to 100 or above and it would have been less luck fluctuation.
There is no way to know if a change in hashrate would have any affect on luck.
Yes, it would potentially give us more blocks per day, but that does not necessarily correlate to an increase in luck.
of course it would have; not on luck itself, but stdev of blocks per day, almost certainly.
organofcorti should correct if i am wrong.
A smaller pool should typically have more variation in the number of blocks mined per day than a larger pool.
to me, this ^^ sounds right.
