@dinamicd...., What Fratemate wrote is more in tune with what i see everyone write on their books...., 5 to 15% of total time is a good ballpark figure and even that is too much in my view..., personally I just write enough IMC not to have to go to the SIM and get requalified...!
Good luck...!
About the authorities catching up..., well, legally we are still supposed to use visual cues instead of our navigation systems if we have visual contact with the ground as per regulations LOL! An FAA big shot told me once..., that the FAR's haven't joined the rest of us in the jet age!
