Comment:
Sounds like a fun analysis for someone who wants to play with stem's new
consensus-parsing module.
In addition to the metric you suggest that is based on absolute relay
numbers, I'd probably add another metric. "If you take a consensus X from
3 days ago and a consensus Y from today, what's the fraction of total
consensus weights that is available for building circuits?"
The output could be a CSV file like this (example data):
{{{
consensus,hours,frac_relays,frac_cw
2012-10-31 23:00:00,72,0.554,0.768
2012-10-31 23:00:00,120,0.341,0.509
}}}
This would mean that, when using a 72 hour old consensus at the stated
date and time, you'd know 55.4% of relays from the recent consensus which
together have 76.8% of total consensus weights.
Useful numbers of hours might be 1, 2, 3, 4, 5, 6, 12, 24, 36, 48, 72, 96,
120, 144, and 168.
As a special case, if no consensus was published exactly 72 hours ago,
we'd look at the one 72.5 or 73 hours ago, and so on.
Having data for the past 12 months would be good. I could help with
graphing results.
Changing component to Analysis, because this task is about a one-time
analysis, not a metrics utility that we'd want to write and then maintain.
