I generally average out to about an hour to get to the final print, and that involves around 6-8 sheets of paper. Once I hit my "final" print, I always do three of them, taking into account the dry down factor. This means I'm only good for about 2-3 fine prints per day as a four-hour darkroom session is the most I can realistically do with an acceptable level of performance. The larger point to be made, though, is that it really does not matter how many prints it takes to get to the final one, as long as your standards are high and the result is beautiful.
