Does it matter who "we" is? Does this add anything to our
understanding of these matters?
Warren Smith has written, and then confirmed his meaning later,

This is explicit that what is being considered are sincere ballots
(ranked ballots, originally), and then Range was brought in, it would
be tedious to track it down, but I think Benham was involved....

Does it matter? If you don't understand me, pass it by; if someone
else understands me and thinks it important, they will perhaps
mention it. And if what I'm writing makes no sense, you also gain by
passing it by.

Again, is Warren's preferred range relevant? Warren has not spent any
significant amount of time advocating that to the Range community. I
noticed the mention that he prefers to allow *any* rating in the
interval. I can imagine reasons for that, but they do not impact what
I wrote. Warren said that he's not advocating such high resolution
for practical reasons. And, I would note, if he thought sufficient
value would be gained, he might well go ahead and advocate it anyway.
But I don't think he sees that. He merely considers it optimum. Maybe
in some elections it would be important. I did mention that there are
conditions where one can calculate exact ratings. Perhaps I'd think
it lucky to rate a candidate at pi/4 + 214.6024/1000.
For now, I will simply note that Benham totally avoided the substance
of what I wrote. I had made an assertion that, essentially, a rating
difference of one point on a scale of 0-99 was "down in the noise," I
think was the language I used. Benham denied this, without
explanation. When I pointed that out, he noted -- correctly -- that I
had not substantiated my claim (I had not because I considered it
obvious). So I substantiated it, and then, at the end, concluded this
with what Benham extracted above:

I did not see a shred of evidence in Benham's post. Did anyone? Does
anyone have such evidence?
(The claim of Benham is that 98 vs 99 (Range Ratings) is meaningful
in terms of the voter appreciation of candidate election utility,
though that is not exactly how he stated it, he stated it negatively,
by denying my claim that it was not significant. It has a meaning,
which is most likely that the voter is voting strategically but
wishes to leave a shred of preference indication.)
