The luck is unpredictable and instable, therefore a pool efficiency vary from a day to an other.
I don't have anything against other pool but what strike me is that DwarfPool claim to be very transparent but doesn't display the efficiency and not even the luck... so how do users compare ?
The only real measure for you miners is how much Monero you get per 24h. The other stats doesn't mean much IMO.
I'll let it sit for a few days to have a fair comparison. The one thing that i found interesting @

You can determine your rigs separately for better vardiff, lower rejects and detailed statistic. Use username with any number (integer, any random number): WALLET . WORKER-ID
..
So I've done that and mined directly to the exchange (walletaddress.paymentid.workernumber).
Personally I like using monero.crypto-pool.fr and I was wondering if there's a roadmap of features you have planned.
