IRV is simply single-winner STV. The term "IRV" (or RCV or AV or 
whatever) is used to distinguish the single-winner method from a PR use 
(and the single-winner case is easier to describe than the quota 
mechanics of STV).

Single winner STV (IRV) is not very good. 2-winner STV is better... as 
the number of winners increase, the constraints are increasingly because 
of the quota and less because of the "in-between" dynamics, and so STV 
gets better with increasing numbers.
