Les There was an article in the PTJ regarding this subject. One point made was to bring the first note ( A or C or whatever) about half as many beats sharp as it was flat i.e. 15 beats flat pulled up to 8 beats sharp. Then rough in a temperament from that note and pull up the rest of the strings. I mute the entire piano using a double strip method, and pull up the open strings. Then I pull one mute out, tune, pull the other mute, tune, then pull up the bicords. When a piano is down 100 cents or more, a couple of passes are required. Work quickly. Don't be concerned with tuning the octaves and unisons. Get close and move on. Two passes should take 15-20 minutes including the muting. Bill Sadler, a former University of Minnesota tech used this technique and said he found the faster he could get it done, the better the piano would stay. This seems to be true. I've used this method on trade ins at dealerships, so I can monitor the results. The piano stays quite well.
