Tom,
Nice work.  What I see is (with one exception) a series of higher-highs and
higher-lows.  The overall trend is up, given this data set...though there is a
hint of a turn-aound at the end.

HOWEVER...this is only 6-events worth of data.  The quesiton is if this is
cyclical (short-term) or secular (long-term).

There is much to know about how to properly define data sets and analyze what
they show.  There's a reason that statistical analysts can make a living doing
it.

The point is still this: Too many assumptions are being made and conclusions are
being drawn based on annecdotal "evidence".
