Hi Terry, My usual tuning time is about 45 minutes *if* it is a repeat client, *if* I was the last tuner and *if* I'm left alone. In this case the stage manager kept butting his head in, so the first "tuning" was 1.5 hours. Then he butted in one more time to tell me how the "other" tech had spent two whole days regulating the piano. Whereupon I got annoyed and played a note. *boing* Then I played it immediately again. *click, click, clickettey click*. He looked horrified. It had been used in two performances, and no one had complained. 230 tuning pins x .5 seconds = 115 =~2 minutes (out of a 5 min pitch correction). There is no way an ETD pitch correction can be faster than say a "deaf" or "blind" pitch correction. It may be considerably more accurate (usually).
