So I'm trying out my luck by solo mining flux. Though trying to get a better understanding of "Personal Luck", I did some digging around the site (2miners) and noticed that the same miner(s) seems to creep in and out from time to time and when they are mining, they seem to just be scooping up a good portion of the blocks. After I find a block (current "luck" is 6% after 1 day) I'll probably move back over to pool mining. But in the meantime, I'm just curious as to why such a heavy miner comes in and out like that... seems like certain times too.
