The current BW auth measurement results are around 1.0MBit/s for greendream848. I had a couple of measurements in the 300-500KBit/s range. So, if the auths heavily weight towards low individual measurements, things might make sense.

Maybe one of the BW auth guys can comment on how the total measurement result is cooked up!?
