The following article by M Schulze ( never heard of him! ) on something
called Quota Borda was published in Voting Matters 15.

I'm not particularly interested (or knowledgeable) about Borda Counts but the
following seems a particularly bad example (whether it works depends on the
treatment/ allowability of truncated ballots):
Year 1
An election is held using Borda for a single seat. There are two candidates
A and B. The voters give the following rankings:
12 A
40 A>B
30 B>A
18 B
A obtains 52 points (52x1 + 30x0), B obtains 48 points (48x1 + 40x0). A wins.
Year 2
This time there are 3 candidates A,B and C. The voters give identical
rankings as in the previous election. Nobody expresses a preference for C making
candidate C the most irrelevant of irrelevant alternatives.
12 A
40 A>B
30 B>A
18 B
This time the points are A= 52x2 + 30x1 and B= 48x2 + 40x1. A obtains 134
points and B wins with 136 points yet identical ballots have been cast in both
elections.
