So I quickly hacked together something to run it through my old 
multiwinner code, but I'm getting unusual results. Could someone check 
that they get what I'm getting?

{C101 C102 C103 C104 C105 C106 C108 C109 C110} for birational voting
{C101 C102 C103 C104 C105 C106 C108 C109 C110} for Range PAV (integral)
{C101 C102 C103 C105 C106 C108 C109 C110 C116} for STV
{C103 C106 C108 C109 C110 C111 C113 C115 C116} for Meek STV
{C103 C106 C109 C110 C111 C113 C114 C115 C116} for Schulze STV
{C103 C106 C109 C110 C111 C113 C114 C115 C116} for QPQ

where Range PAV (integral) is like PAV, but each rating is counted as a 
fraction of an approval. See

 Sainte-Laguë or D'Hondt doesn't matter for this election, it seems.

If it seems to be right, I'll give the results for a bunch of other 
methods, too.

According to the program, the reduction of the ratings to ranked ballots is:
