ESPN's headline tease claims that TV viewership for this year's WNBA playoffs has "doubled." It's apparently not true, but the truth is cool enough: finals viewing up 73% (compared to last year's one-sided shutout), playoff viewership overall up 54% (that's one-and-a-half times last year).

Where does "doubled" come from? The Nielsen ratings, which went from .2 to .4: it's the large rounding error produced with small numbers-- small, that is, compared to the total number of televisions in the United States, but perhaps big enough, compared to what the league needs.
