It's funny that amounts paid before costs are fluctuating all the time in line the Bitcoin price. If it's high it seems you get better amounts and if it's low you get less which is crap.

For a start the pool should be by itself on all the miners working together and then you have their own farms mixed in aswell. They used to display the users and hashing power which they don't show but last time I saw users hadn't risen and hash power wasn't a noticeable rise so why the less rewards. They upped their own farms.
