Can 2011's ever get more than the rated battery life?

Specifically the 11 inch but 13 inch owner inputs are welcome too. From my research the 2010 core 2 duos can exceed the rated 5 hours of use but has this ever been demonstrated by 2011 models? It seems to be more common to have 3 hours - 5 hours of battery with many not being able to reach the rated 5 hours.

Take note that these are just from averages and data from reviews that I have read. What is your average life with just normal day to day usage? I know that they will vary greatly with some only getting 1 hour of life from extreme usage but my goal is to see if anyone has exceeded the 5 hour mark that the laptop is rated for.

My personal i7 11 inch air lasts 4 hours 30 min with iTunes and mail and messages on, keyboard and screen brightness to 50%, and browsing on Safari with the clicktoplugin enabled which greatly helped bring my battery life within the rated specs (which makes sense as apple gives the rated battery life with no flash enabled).I also watched about 10 minutes of youtube HTML5 video when I tested. With Flash allowed to run wild it can barley get 3 hours 20 minutes of use. The battery has 116 cycles and is 11 months old.
