Again to be a little critical, a MB on average every 9.1 seconds is a bit high, that number should fall between 8 and 8.5 seconds when playing extremely well but sub 9 is very achievable.
As others have pointed out, the lack of buffs is not doing he/she any favours but a quick look at their gear shows it's hardly optimised to do great DPS either. So in terms of how they are playing, they are playing better than most but not as good as possible. Gear is a limiting factor and missing decent buffs to help them perform well.
