[tor-relays] bandwidth authority algorithm is cracked

The bandwidth authorities assign all kinds of wildly incorrect capacities to the Tor node here.

The Tor relay software has been up for 45 days and has not been down for more than five minutes for three or four months.

Occasional outages from the ISP mucking with their network, but nothing more than ten or fifteen minutes in any week.

The local node bandwidth calculation is consistently 490-495 Kbytes/sec. Very stable. Very consistent.

The Tor bandwidth authorities assign values anywhere from 100 Kbytes/sec to almost 700 Kbytes/sec in an oscillating pattern with a period of about one week.

Something is seriously wrong with that.
