Consensus weight of my relays and those of others is still near zero, and not improving. . .
I read the earlier discussion around this issue with interest. Have no specific ideas about resolving the problem, but I can recommend pulling the raw text data files for the authority votes, grep'ping your nodes, and looking at the specific BWauth votes over time.
The data is found here
https://collector.torproject.org/archive/relay-descriptors/votes/
and while the files are a bit huge, are easy to whack at with *nix command line tools such as egrep/awk/sed/perl etc. In a pinch one might apply Excel to the problem, but first trim the data set down to size with a grep or your desktop and Excel will choke and die.
I did this at the point where the bandwidth for election to guard status was increased greatly and my node was shipped off to middle- relay mediocrity. Could see clearly how it all transpired, but of course I could do nothing about it short of spending more $$ on bandwidth.
With the raw data in hand, it will be easier to campaign the operators of the troublesome BWauths to correct the problem.
