Some possible fallout related to the earlier discussion
[tor-relays] amount of unmeasured relays continuously rising since 2 weeks https://lists.torproject.org/pipermail/tor-relays/2015-May/007003.html
My relay
Binnacle 4F0DB7E687FC7C0AE55C8F243DA8B0EB27FBF1F2
has 9375 Kbyte (75 Mbit) of unfuzzy (no ISP traffic shaping) bandwidth, but in the last few days the BWAuths' opinion went from
# gabelmoo # tor26 # moria1 # longclaw
bw1-w Bandwidth=7382 Measured=7100 *bw2-w Bandwidth=7382 Measured=9330 bw3-w Bandwidth=7382 Measured=13700 GuardFraction=69 bw4-w Bandwidth=7382 Measured=23700
to
bw1-w Bandwidth=9375 Measured=17100 bw3-w Bandwidth=9375 Measured=77900 GuardFraction=75 *bw4-w Bandwidth=9375 Measured=23000
* selected for consensus
While it's flattering to be promoted to double the actual capacity, with the potential to go 8x, I suspect it's may not a great idea in the grand scheme of things.
And to think at one time I was feeling short-changed. . .
FYI BWauths

Should probably add that this relay was tuned and would be expected to show somewhat better performance than a typical relay of the same capacity, but I wouldn't expect more than a 20-30% boost from that.
The local bandwidth observation was, at the time of the consensus sample
published 2015-05-20 07:33:13 bandwidth 9375000 9375000 9713664

Keep in mind that the bwauth weights are all relative, unit-less numbers. They're not bandwidth values; they're fractions of total weights. So at least in theory, it can be totally fine that your relay has a very large weight, because it has to do with the relative chances that clients should pick your relay compared to picking other relays, not "how much bandwidth" they think your relay has.
That's not to say that we're computing these weights in the optimal fashion at this point. But hopefully it will help you and others have the right intuition. :)
