We look at the difficulty of mining machine display, and BTC or LTC is not difficult, as does the ability to dig up and took us count BTC and LTC go, please check to make sure!
Kind of a incomplete sentence so I am not sure what you are asking but it sounds like you are saying that difficulty doesn't match coin output? If so that is the same thought I had as I would of expected a higher/faster coin gen with what is being thrown at it right now.
