FW16 180W power brick efficiency


Has anyone measured the efficiency of the FW16 180W power brick?
For desktops, one has the gold, platinum, titanium words for approx efficiency of psu. Is there anything like that for laptop psu bricks?

So, can anyone tell me whether the fw16 180W power brick is 80%, 90% or whatever efficiency, it would be nice.

91.3% with 120v AC.
92.6% with 230v AC.
