Just ran a 12 hour experiment on the exact same 1060 rigs.
Average shares per hour:
Claymore 11.4: 152
Phoenix 2.6: 174
Extrapolated over the month, Phoenix provides 0.08 more ETH over Claymore.
2.7c crashes every so often for me, and just yesterday my virus program deleted the executable so I've gone back to 2.6.
but what was the difficulty of the shares? it is pointless to count shares as each one can have a different weight. for all that you know claymore 11.4 can provide more eth than the 174 shares. so how did you get the 0.08 eth?
