Where did you get the information that MtRed's is 0.0000167805 PPS?
Their website, front page. I've actually crosschecked with the # of shares I submitted to the pool and the payout, and it was indeed 0.0000167805. As of now the website has removed that information from the front page. It WAS odd, he was paying double to everyone.
http://webcache.googleusercontent.com/search?q=cache:hTMbYhjyAKYJ:https://mtred.com/+&cd=1&hl=en&ct=clnk&gl=usHere's a past google cache when difficulty was a little higher. It's still 0.000014 ish. I think Mt.Red's been paying double for a while.
EDIT:
The info is back up on Mt.Red now (still 0.000016). Although I can't connect to their mining pool.
