I'm not the smartest. but I am pretty smart - there are others like the person who has figured out WDC's block generation algo and time his machines to jump on wdc multiple times per day right before the block chain starts popping blocks in order to maximize his profits. Once you figure out there are people have have huge advantages over you in this field it puts a lot of things into perspective. Mining is not fair and you need every advantage you can get - which is why I developed SmarterHash. My members can chime in they choose, but I suspect they'll remain silent - they don't want competition that  dilutes their profits.
