whether these failed downloads got 0 bytes or 'most of the bytes' before
failing?

The downloaders do not "give up" unless the socks connection is closed by
the other end. Although, I now realize that its probably smart to have the
client "give up" so as to avoid knocking it out of the simulation because
its download hung. Doesn't Tor kill the AP connection if it can't get a
circuit by a deadline?
I do not explicitly count failed downloads, but I do track bytes received
over time. So we could count partial downloads that never completed, and
infer failed downloads as partials that were started before the last X
minutes of the simulation (to avoid counting legitimate in-progress
downloads as failed).

Its running now:)
