Hello, When tuned in HT, or even alternate quasi ET, the instability will not be hear because it is very few musicians only that can check for example the color of a tuning and say if they agree with it (I've experimented that in tuning 2 instruments in reg meantone for a small ensemble for 12 days) When the people will accept an alternate temperament, they will accept that their piano will be less in tune in fact than with ET. ET is not very forgiving, the more precise you are the more easy the flaws are heard (and the unisons may be very pleasing for the piano to give its full color) . It is way more difficult to hear errors in HT or alternate (but in octaves , doubles and triples) Very few of my respected colleagues here tune very perfect ET , and indeed since I use VT100 to extract the best ET tuning of the pianos, some colleagues have complained that they don't have the time to produce a so even result, they can't correct the tuning in the same way, because they prefer their own temperament sequences, with difference as large as 1.5 t0 2cts in the temperament. As their sequences differ, their results differ too. With time, we have found an acceptable standard but, some notes are more prone to move than others. If I am in a hurry, the game I have is to found the temperament sequence used lastly, so I can tune in the mood of the precedent tuner. If I have time, I use the VT100, but I check tonally (fifths and twelve's) to keep an ear in tone color, even if the "perfect ear" ability tend to push me towards a very pure ET. Beside, the very little moves, are not very hard on the global stability of the piano - 2 cycles mean a lot more that these little tweaks.
