This is my hashrate and stale share percentage in Claymore 11.6
https://image.ibb.co/iz6vBc/ETC.pngPhoenix can tap my RIG up to 395Mhs (13GPU) however, it gives me 5-6% stale share..
i like the hashrate spike from PhoenixMiner, but i guess effeciency goes to Claymore 11.6 - hope that PhoenixMiner could catch up soon..

I'm waiting on the same fix for stale shares.
I have almost identical results with speed gain but stale shares are just too high with Phoenix.
When that gets solved I'll be back on Phoenix in a flash.
