Hello,
i tried to use this pool, but why more profit
http://nrs.blockquarry.com/ ? although the same level of difficulty.

.
sorry for my stupid questions

Regards,
The payout will average out the same as we are using the same pool server and mining software. However until more miners join the pool finding blocks will be very random. Since most are on Block Quarry it has more consistent payouts and block discovery.
However I would encourage more people to join Flip Side Mining so that we do not have one pool representing nearly all the network.
hahahah..
