I put down >75% as I use the diesel only when necessary. I will sail into and out of my berth whenever the wind is accomodating. While I mostly race and day sail now, when I used to cruise a lot with my wife I used to sail off the anchor very early in the morning and have some of my most memorable sails while she was sleeping down below. She is NOT a morning person.
That being said, yesterday I dropped sails and motored in at 6 when the wind went very light in a 25 mile race. When it goes light around here in a high it will not likely fill in for hours. My four 19 year old crew members all had some good looking plans for the evening waiting for them on shore.
