If you dispute this, then please show a graph or table with the peaks labelled and the years shown against the years of sunspot maxima or minima.
Thanks Ray, in JimP’s chart of sunspots against barycentre, you can clearly see the minima alignment to the 178.9 year cycle. I take your point that this is not proof of a physical connection, given that the average sunspot period here (178.35 years) is half a year less than the SSB cycle, producing a very small drift forward of sunspots against each SSB cycle. Comparing the periods 1734-1755 = 1913-1933 you can see the SSB and sunspot minima are both directly aligned to the Jupiter-Saturn cycle. I think this is worth further study. The data for these patterns are here.
