Comment 16 for bug 140458

Steve, as mentioned a few times it does not have to be anything scientific. And it is perfectly possible to start with equal weightings and then change it later. Nevertheless location and subjectiveness can account for so much when the bandwidth difference is or order of magnitude... Having 3 to 5 large buckets for preferences (say 75-50-25) would compensate quite well for differences in location/subjectiveness IMO. Particularly since such preferences would mostly be relevant when the local mirrors are out of questions.
