Understanding Root Lifetime DELs at fixed Mean

I am Programming a PI controller, using IPC for a 5MW Land DLL turbine. I am Plotting pitch activity against DEL to figure out an appropriate gain for the controller. I am Plotting RootMyb1 DEL, at fixed mean for various S/N Curves. The question I am asking:
Is the closer the match of this RootMyb1 DEL to the total number of equivalent cycles the proper analysis. As in, the values I get where RootMyb1 is closer to Total number of equivalent cycles are more accurate?
Any help would be greatly appreciated.
Kind Regards,

Dear @James.Morrison,

I’m sorry, but I’m not sure I understand your question. Can you clarify?

Best regards,
