Does fractional STV really throw away fractions of those ballots
which are truncated?  Is that better than keeping them and 
transferring larger fractions of ballots which didn't truncate?

I'm not sure what you mean about the fringe candidates getting votes.
They wouldn't get votes of people who truncate them away.  Do you think
the fringies would be truncated away less than other candidates?

Perhaps you misunderstood my poorly written paragraph.
