Am I doing something wrong, or is Bing search on WP7 really this bad all the time?

It's a problem I've had from day one, but I've never thought to ask about it until now. It is absolutely abysmal. The other day, I searched for "73 as a percentage of 78", and the first result wasn't even a maths site, it was "US seat belt percentage up to 73". I can't believe the level of bad it is, I've actually downloaded the Google app, which sucks, but at least the search results are decent.

Have I got something wrong in my settings or something?
