This isn't how I generally understand the concept of sincere voting. In a
ranked ballot system, I would hold sincere voting to the following
definition: 

If you rank candidate A over candidate B, that means that in an election
only between A and B with no third option, you would vote for A.
If you rank candidate A equal to candidate B, that means that you would
not show up to vote in an election between A and B with no third option,
or, I suppose, that you might show up and vote for both of them, whatever
that might accomplish.

Anything else seems to me to fit under the category of strategic voting
rather than sincere voting.
Note that I'm just talking about ranked ballots here. Definitions of
sincere voting for approval and plurality are not quite as clear to me, in
fact I'm not sure that such definitions can be firmly established.
