...in six distinct descriptors, each containing 10 intro points, each of
_those_ attached to one tor daemon.

Correct.

which lead me to believe that a single client will not

Strictly, the way that Tor works, the client will query the HSdir and
receive 1 (one) descriptor, of the 6, containing a random selection of 10
introduction points.

Aha!

Each of the 60 "actual" Tor Daemons sets "NumIntroductionPoints = 1"

Then the OnionBalance software creates one more, virtual, somewhat
"parasitic" set of descriptors - which comprise the 6x10=60 alluded-to
above.

Any given introduction point in the parasitic set of OnionBalance
descriptors, is actually a descriptor stolen from one of the 60 separate
daemons (- these daemons having set NumIntroductionPoints = 1)

Is that a better explanation?
