Now it's not, long periods are not indicator of quality. I was responding to the chance of unexpected repetition of sequence because of collision of entry points. Long periods is an indicator that the chance of entry point collision should be low enough. Long periods (alone) doesn't mean anything to the quality of the randomness itself.
