They're all the same timewise. Pick large pages, they

Yes. There are 3-4 barely visible steps
interesting in the thick blocked line too.
I put 10min on the fetch, but those steps around
120-150 could also relate to some stack timeout
in the fetch - webserver path. Nor is the
test machine quiet.

All as before, of the blocked exits, a sizeable fraction of
the ones around 120 sec had a consensus weight of
zero. No idea.
There also seems to be a topleft to bottomright
diagonal line weight density split.

Afaik they don't ...

However long it takes your fetch to return.

Reduce the variables... one page of html.

Doubt it. But try tor-resolve and traceroute to see
what they're doing there. Afaik they are strictly in SFbay.
I can't tell more on the 50/50 time split without also, regarding
possible nagging abuse, at least checking the percent
of 'recently new ip' relays in the 1200, and probability of
being chosen exit from 1200 (I was trying correlatin weight
to blocking, but inconclusiv or i have wrong weight metric).
