Yes, please. FPTP is the worst.

Does this imply an STV variant where surplus votes are transferred, as 
discussed below?

Wikipedia says that once someone reaches the quota (which I think is 
Bill's "election threshold"), they are declared elected. In a two-seat 
election, I think that threshold would be 33.3% (plus one vote), so 
candidates three and four have crossed it. They are both elected, and 
since both seats are filled, the process stops. (Your example arrived at 
the same result, though.)

It should only be necessary to distribute excess/surplus votes if only 
one candidate had passed the threshold and there were still more 
candidates than seats.

According to Wikipedia, only some definitions of STV transfer 
excess/surplus votes. And there are different ways to transfer the 
surplus votes:


I don't have strong feelings about those details. But whatever ARIN is 
adopting does need to be clearly specified somewhere.
