No, of course I wasn't asking for the ballots of any voters by name! Perhaps
I should have been clearer: I was asking for the data in tabular form as
given (for a hypothetical example) at

Since the Cambridge administration (University, not city as it happens)
are well aware that there are problems with the arrangements for ballots,
principally due to my speeches this year although there had been a great
deal of unsatisfactory happenings last year too, I don't think that the
worry is of that nature (or at least not mainly). Also these are
referenda on issues, rather than elections of candidates (for which
the regulations were overhauled some years back to use "a more modern
form" of STV than the one they'd adopted in 1926), so I don't think there's
much fear of a losing issue suing!

Not this electorate. Maybe *one or two* people within an electorate that
now numbers some 3000+, but a much greater problem is that a good third
of those who vote seem unaware of what they are doing, some even still
believing it's a FPTP system, or that a single transferable vote means
they may mark only two options.

Swings and roundabouts, I fear. This is part of the problem where there
is no true best voting system. But on issues rather than candidates I
think that trying to give greatest satisfaction to the greatest number
to be important.

I think that that depends on one's definition of trust. Certainly there
is a significant proportion of Cambridge's academics who do not trust
the central administration here. Unsurprising: controversial things have
been hidden from them and then presented as a fait accompli.
Why should the central administration not be able to trust me? I am an
academic, albeit quite low on the pecking order, and I adhere to such
things as academic integrity etc.

Note the use of the word *advocate* there. Of course any advocates of
any system are going to use something that appears to be in favour of
their cause to attack their opponents. (I get the impression you are an
IRV advocate, frex.)
But what I want to do is to come up with the best solution *for Cambridge*.
The results of Graces 5 and 6 as shown at
cause me profound worry. I don't think either result is likely to have
reflected the wishes of the voters (not the least because of the way the
matters were presented to them, conflating two issues of almost orthogonal
relevance into the wordings of the options).

I'll chase them up; I think I have them somewhere. But was this an
edge case where any of the paradoxes occurred, or any important criteria

I live in hope that one day I might find such a group of knowledgeable
voters, all collected in one place and willing to fill out ballots for
academic study purposes ...
