Thank you for clarifying.
Can we avoid this ambiguity for the future?
One possibility is to use an "&" (ampersand) between two choices that
are ranked at the same preference level. For example, approval ballots
would look like this:
10 voters: A & B
10 voters: A & C
When ranked ballots are used, there can be a mixture of same-level and
10 voters: A, C & B
10 voters: C & A, B
Another possibility is to omit any symbol between same-level choices:
10 voters: A B
10 voters: A C
10 voters: A, C B
10 voters: C A, B
Obviously I'm used to a comma indicating a change in preference level.
Am I the only person who interprets ballots this way?
BTW, in my opinion a voting method that does not allow a voter to rank
two choices at the same preference level is not a good voting method.

I suppose that by limiting the preferences that voters can express, an
approval approach might appear to achieve better proportionality.
Yet I think that if full voter-preference information is suppressed, we
are doing what single-mark ballots now do: hide the unfairness by not
collecting all the relevant information.
