For Ethereum the value is correctly higher on the single profile, as it also includes SIA for dual mining, while it's not for the group profile. I will have to investigate if there is a problem with group profiles not including secondary coins correctly - that's the only scenario I can think of right now. I will get back to you on this.
Thank you.
I just witnessed how a switch from EHT+SIA to ETH+DCR didn't include the correct command line, even using my single profile. I checked the log and found where this happens. Only included the relevant part to see that it came from ETH+SIA (line 4, command at line 57), profitability for DCR got higher and then the switch happens at line 291 (command at line 330).
