What I really wanted to say was this "news" of a 3/10 point increase is not relevent, much like Bing results.
Also, for what it's worth, I now use Bing as my primary search engine and find it produces highly relevant results. I attribute this to performing tightly targeted search queries. I feel that Google is still better for serendipitous (exploring type) searches.
I think he is saying it is statistically irrelevant. Such a small increase in such a small time period could be random "noise".
