Rails Timing Log Incorrect?

Hello, I'm trying to understand the following log message: "Completed 200 OK in 689ms (Views: 586.6ms | ActiveRecord: 2522.1ms)". Shouldn't Views + ActiveRecord <= 689ms? Or am I misunderstanding the output?

Rails 3.0.5, Ruby 1.9.2p180 w/ gcdata and gctuning patches. output is from running "bundle exec rake test:benchmark". Any thoughts?
