So this is what I am getting on MSI Armor Rx 580 8GB OC.
Per card in dual mining mode
ETH : 31.43Mh/s Blake2s : 15300Mh/s (XVG)
Estimated daily earning is 14XVG
( This is according to what to mine)
Comparing to lyra2rev2 single mining
lyra2rev2 22741.0 Kh/s
Estimated daily earning is ~30XVG
This is based on what I am getting now.
I now plan to keep only 30% of my hash power for XVG single mode mining and rest in Dual mining with Eth.
You must be using the wrong Verge calculator. The daily earnings for XVG with 15300 MH/s on Blake2s is 141 XVG.
