Here's where I got the data:

 4. Group Sunspot Numbers (Doug Hoyt re-evaluation) 1610-1995
http://www.ngdc.noaa.gov/stp/SOLAR/ftpsunspotnumber.html#hoyt

ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/SUNSPOT_NUMBERS/GROUP_SUNSPOT_NUMBERS/yearrg.dat

Two other sources of the 10.9 to 11.03 main cycle have been suggested:
1) Jupiter tidal effect (orbital period of  Jupiter
 11.86 years)
2) Tritium -- Half-Life: 12.32 Years

Jupiter has about the same mass tidal effect as Venus with has a more
rapid orbital period of 0.815 years. No beat effect of the two seems to
fit the cycle.

Tritium cycles seem unlikely in the sun: carbon cycles 
are more likely?

It appear that the weather hypothesis is the best as of now for the cause.

  <pre wrap="">Dear Roger,

Yeah I had a look at the graph it looks like the oscillation of the
sunspots 
is on a climb, this could be because of several factorials, but 
fundamentally it means from my understanding that a layer in the reaction 
that is the sun is probably reaching a finality point that is increasing
the 
sunspots, also remember the data you have now is conclusive the database
of 
information back before our ability to properly measure this would leave
you 
with an inclusive result, but not a true spectrum.

In conclusion,  this fractal approach to sunspot numbers
seems to have some virtues over a simple "beats" of cycles approach
or the Mathematica neural net approach.
