Wow, what a dispersion. I'm not calling into question the effort,
etc., but seeing these numbers makes me wonder about the value of the
results. The reasons for my suspicion are:
1) That there such wide variation
2) from sampling just a minority of the root ('s 13) "nodes"
3) considering that the topology/architecture of each sampled node is
vastly different
(I should ask - for, say, F, are the samples across all nodes of the
[F] any cast cloud or just sampling at a few of the node's any cast
members?)

Never confuse activity with progress. Activity pays more.
