I take anywhere from 20 minutes to 2 months. My wash setup is in garage so it is not included in this time estimate.
Even with good negative, it takes me quite a while to get the contrast right and density right. With modestly complex manipulation, it can easily run more than a day to get it right.
I don't care about efficiency If I'm printing on fiber, it is a good image that deserve to be printed to my satisfaction. So I take my time and do it over-and-over until I am satisfied with the result.
