Hi Kevin,

Really interesting project!

Won't this severely taint your "ground-truth" though? If you're ultimately
using the exit-node for both, then you'll really only end up measuring what
is friendly to the Tor Browser itself instead of Tor overall. Is that the

If not, with direct access to an exit node, you could run the test direct
from that node (not using Tor) for the "ground truth" and then use it as
the exit node of choice for the Tor Browser to have a solid comparison
between Tor vs Not-Tor.

I look forward to seeing this come together!
