Precisely!! 

If enough other voters pick on the same "loser" because they are playing
the same game, your "loser" will become a "winner".  There is good
evidence from real public elections with STV-PR that attempts at
tactical voting of this kind are unwise.  The only good advice for
STV-PR public elections, i.e. with large numbers of voters whose
preferences you cannot possibly know, is "Do NOT attempt to vote
tactically.  Vote positively for the candidates you really want".
