Some work has been done in this area recently. Can you run with the latest btrfs-unstable tree? Df will tell you something that is more along the lines with what you are expecting, and you can use the new btrfs-progs-unstable tree and run a btrfs filesystem df /mount/point and it will spit out specific space info that will be helpfull.
