Hello,
It was a real pleasure for me today coming back to this thread.
I have some good news about Chas and I would like to share them with you and... not only that.
Since 2011, I could do three biennial seminars at the ITEMM (Le Mans - France), for beginners, advanced students and for professionals. Likely the feedback I got were very encouraging.
In 2012 I could post a recording, piano and orchestra (Rachmaninoff - Concerto n. 3 - second half), for people who believe that an orchestra goes with a different tuning. I dedicate this posting to Sigasa, as he recorded an excerpt, after having fixed a new tuning settings on his keyboard.

In August 2015, Haye Hinrichsen, a physics Professor from the University of Würzburg, published a paper where he compares the 12th-root-of-two ET with modern ET's, pure fifths, pure 12ths and Chas, basing on entropy. His work seems to confirm the value of "stretched octaves" also for "harmonic" tones, meaning with no-iH tones. Here is the link:

Last June I was enabled to do a seminar in Toronto, invited by the Piano Tuners Canadian Association (CAPT) at their annual convention. It went well, the colleagues' comments have reinforced my determination towards more sharing.
Today I came back here, as the Canadian colleague and friend Ernest Unrau was asking me a question about PianoTeq users. I re-read our posts and was touched again by your openness, your understanding, by your words about my family and all the efforts you made to overcome any language barrier and some technicalities.
I want to say thank you, again, for all that and for trusting my words. Hope you are still enjoying tuning, hope to hear from you.
Kind regards,
Alfredo
Edit: I have noticed that the link (above this post) to the "CHAS Tuning mp3 - 2011 - Live recording on Fazioli 278" is not working on my laptop, the following works:
