Short term - it's all about luck
Long Term - Higher hashrate = more blocks found
Go figure we have a blockbuster day, 1 day before I get my shipment of 5 more Block Erupters... BOOO!
remember when the Pool was around 12,000 gh/s! OMG!
great 2 months of mining and an XFX card has a bad fan... cheaper for me to get a replacement than to send it back on its lifetime warranty to be fixed OMG! haha
I wish I had the hashing power I have now, back then... I would have been raking in the coinage! or as my lovely girlfriend calls them.. "BTUs" haha
