[tor-relays] Bridge to Relay Balance Notice

As far as I know, bridges are currently not under heavy load.  This is
because not everyone connects via bridge. Moreover, even if everyone
did, and nobody used onion services, the total bridge bandwidth should
be exactly 1/4 the total bandwidth. Onion services require 5 (or is it
6? I think it's 5) public relays, so if everyone used bridges but
everyone also used onion services then the bridge bandwidth should be
1/6 the overall bandwidth. But, as I said, the proportion of users
connecting via bridges is much smaller than 100%.

As an aside, the ratio of counts is a poor estimate for the ratio of
bandwidth, because bridges have much less bandwidth available on average
than public relays.
