Ron N, I like what you're doing. I see that you are in your robe with the sneakers on and your wrists taped. But I don't see you ready to climb into the ring, meaning when are you going to take those measurements yourself and then tune the duplex scale and then take some more measurements. Theories are valuable up to a point in piano technology as I know you know. My estimates of 1 to 5 times are good and I will guarantee that they have proven to be true. I will also refund your money for any tools and products you buy if you are unsatisfied with them. But I will charge you to show you knew what you were doing when you tuned the duplex. I do have an objection to the tone of your message, however. And that objection is "You apparently want to be King of the HIll, and want to demean and depose CFT Steinway as the inventor". Before you continue this attack on such a prolific, accomplished, dedicated and humble icon you should at least tune a half dozen duplexes yourself. Then your expertise, ingenuity and devotion may be worth recognizing. Until then, it is suspect. Don't stop there. We are all interested in your progress. Dan Franklin
