If you read that before, you should have taken notes when reading "75
minute sessions" and "300-seat auditorium."

 
Note that there were TWO 75 minute sessions.  I know little about
string instruments, but I assume that they are much like playing a
piano, with which I'm more familiar.  I need about 5 minutes to become
accustomed to the keyboard and 10 additional minutes to "warm up"
which is mostly loosening the finger muscles.  However, playing the
remaining 60 minutes, in one sitting, seems rather excessive,
especially without intermission:

Besides an intermission, some time should be allocated for the
musician to tune his violin and apply the necessary rosin.
 
Do you have a link to the source of this test?  This seems to be your
source:
<https://www.science.org/content/article/elite-violinists-fail-distinguish-legendary-violins-modern-fiddles>
It's behind a paywall but is easily bypassed.  There doesn't seem to
be any new information on the testing details.  So, I go to the
source:
"Soloist evaluations of six Old Italian and six new violins"
<https://www.pnas.org/doi/full/10.1073/pnas.1323367111>

I didn't read through all the information there, mostly because I've
read tons about this issue, and violin acoustics in general, over the
decades. Our department had a budget line item for Library purchases,
and I think the most expensive item I ever requested was for a book on
violin construction written by a team of two brothers who were part time
luthiers, one of whom was a machinist, the other a degreed Mechanical
Engineer. Their innovation, as described in one of my journal articles,
was the construction of several measuring tools to consistently measure
bending and torsional resistance along different axes of violin tops and
backs - an operation generally carried out with bare hands and judgment.

But over the decades, articles on violin acoustics, etc. have appeared
in many technical journals, plus popular scientific publications like
Scientific American. I probably have phototcopies of some of those
articles in my pre-internet filing cabinet.

Again, comparisons of Strads (and the like) vs. top quality modern
violins have taken place since at least the 1800s. Dedicated experts in
acoustics, instrument construction, materials, etc. have been very
curious about this issue for a long, long time. Look up Ernst Chladni
and the use of Chladni Patterns to analyze the vibration of complex
plates, like violin tops and backs.

But that matters little here. Our little local "skeptic" is perfectly
convinced that he (who has probably never played a violin) knows as much
about violin acoustics as Chladni or Stradivari or any other acoustic
expert; and that what he doesn't know is just a matter of opinion, with
every opinion being equally correct; and that all tests are biased, in
particular those that give results that are at odds with his
predetermined but ignorant opinions.

I assume Krygowski is referencing me... and, so;

I never claimed to know anything about violin construction; I have no
interest in violin construction.

I also have no interest in other people opinions about which violins
are best. I believe that the better test is how well someone plays an
instrument than the tonal qualities of the instrument itself. A good
violin player can make a poor quality violin sound very good, but a
Stradivarius will not make a terrible violin player sound good.

As for all opinions being equally correct; No, my opinion is always
the best one, but if I believe someone else might have a quality
opinion, I may read what they wrote or perhaps ask them. I may
consider what they say, but the final analysis is that my opinion
reigns supreme over all other opinions.

However, I am not inclined to try to convince others unless their
opinions effect me, and that is a very rare occurrence.

By the way, Krygowski, I decided long ago that your opinions have no
value at all, so there would be no value for me to try to change them,

...and finally, yes, I believe all published studies and polling is
biased, and even if they weren't, I don't care what their group
thinking conclusions are. Unlike you, being part of a majority opinion
is not one of my motivations. I have no problem being singular.

I know you don't understand that, Krygowski. You're driven by your
pathetic need to be accepted and valued by others. I only require
being happy with myself,  and I am.
