[tor-relays] Consensus Weight calculation

You mean 0..1 weight (1 KiB/s and lower)?
They may be really bad.

I guess, that good test range is 10..20 (or 5..30).

Relays can be additionally filtered by Stable flag (or uptime).
If relay haven't rebooted for weeks, there is a big chance that it will
  stay online during the tests too.

I hope this will give more successful attempts.

If larger set will not give better results, I will try to make
  my own test program and launch it from my location.
Maybe different approach will give different results.
I am still sure, that low weight estimate is hiding many fast relays.
