I agree that a link to a more substantive writeup would be very good… it’s hard to know what to make of the claim that “Pianists with a long professional experience show a statistically significant preference for the aurally tuned grand”, given that there were only 8 such pianists and 2 pianos (one tuned one way, one tuned the other way).
… also, this information comes to use from the website of this “entropy piano tuner”, which seems… well, I’d like to see another source, at least.
If there was a consensus among the 8 as to which tuning is better, that would be significant, right? Since the chance of that is 1⁄128 if they can’t tell the difference. You can even get p < 0.05 with one dissenter if you use a one-tailed test (which is maybe dubious). Of course we don’t know what the data look like, so I’m just being pedantic here.
Thanks!

(Apparently, the creators of this “EPT” are themselves affiliated with the University of Physics Würzburg, which certainly explains how/why they got the University of Music Würzburg involved in this test.)
To reach statistical significance, they must have tested each of the 8 pianists more than once.
