   OK. I didn't pick up the paper contradicted the OP's characterisation.   
      
   But to make up for that slip I will ignore the followup and add some details   
   here.   
      
   Using a direct & "smoothing" (aka optimal binning) TS regr we can   
   look again at the number of large eruptions vs solar activity (using sunspots   
   as a proxy and the wiki list of 20th cent eruptions). This time   
   y == number of sig eruptions in each year with x == avg SSN in the year,   
   as before.   
      
      
   MODEL:   
   y = -0.00350263*x + 1.60928   
   beta in -0.00350263 +- 0.00245532  95% CI   
   P(beta<0.000000) = 0.996201   
   alpha in 1.60928 +- 0.232442   
   r2 = 0.31936   
   calculated Spearman corr = -0.435065   
   Critical Spearman = 0.368000 2-sided at 5%; reject H0:not_connected

   (Points from the dataset are allocated to bins. Each point is   
   allocated to the bin which is "closest" to the data point   
   in terms of SSN & count in this case. The bin gets labelled randomly   
   from the year of one of the points that got allocated to it.   
   So "1933" means "years like 1993 in that av SSN ~=5 and av count ~-2", &ct).   
      
   Which suggests (together with the prev regr) that   
   a "background" rate (year with minimal solar activity aka SSN around 0   
   as approx now) of eruptions is around 1.6 eruptions per year   
   with an avg VEI around 3.8.   
      
   When solar activity peaks that drops down to less than one per year   
   but slightly larger VEI.   
      
   This pattern then tends to confirm with a robust test what the paper was   
   saying and contradicts what the OP was saying.
