I just multiplied my BandwidthRate with a bit for my exit.

Good job, thank you!

Looking at the advertised bandwidth vs bandwidth history from Tor
Metrics[1], it appears that guard relays see much more traffic than exit
relays. I think it might be partially because guard-only, guard-middle and
guard-exits aren't separated, but would it really skew the numbers that
much?

Don't forget that some traffic enters through guards but lands on
hidden services, skipping Exits.

But hidden service traffic makes up about 0.01% of Tor traffic.
Total is about 75Gb/s:

Hidden services are about 900Mb/s:

Once a net reaches adequate bandwidth capacity, adding more
nodes can do a few things among others...
Good:
- Gives operators deployment experience till their bw is needed, at $cost.
- More non-evil relays gives better odds of building a non-evil path, but tor
weight's things so not exactly.
- May add some capacity for directory operations etc
Bad:
- Yields rather unused nodes making it easier for passive
observer to see you tack up and use a path through them,
especially if you're crafting paths.
One key here is probably that we don't have a good idea as to the
quantity of evil nodes, or the hard interest and real capabilities of PA's.
To make the call you'd need that, and perf metrics of your net under
different ratios of advertised:consumed:nodecount, and min/avg/max/stddev
of idle/random/full paths, to find any sweet spots / ranges.
Also considerations of impact adding nodes of less bandwidth or
more latency than average, versus a campaign to fund replace them.
At 42% util by one metric, it may be money and time better spent
elsewhere, even on better qualifying the default 'more nodes good' idea.
