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.
