Tkamiya: that's exactly it. I appreciate your perspective. In the end, I don't want to spend more time than it's worth, although, I am sure that there will be prints that will need extra special attention.

For most of my life, I've been a professional violinist. I know how much time it takes to perfect something and, alternatively, how much time it takes to make it performance ready.

Efficiency is about maximizing return for efforts, and at some point you cross the point of diminishing returns. I was asking for average time in the DR for one print so that I'd have some point of comparison for that measurement.
