✘minpoll=maxpoll from 1 to 6

[Gary E. Miller]

Yo All!

New data for poll=5 (32 Sec).  Like before, all data is 90% bounds,
run over 24 hours or more.  Clearly the proper minpoll=maxpoll is
important and non-trivial to find.

Moving slowly from 1 to 6 seems mostly a good direction.  7 is next.

Clearly poll >= 4 is past the optimum point for this host.  I think the
winner is poll=1, but poll=2 or 3 are close.

More to come.
