A lag between event and effect? You've got me curious, and I'll check it out. The phenomenon is very well documented at this point. The 11-year cycles (within large cycles, I think) have been followed since the 18th century.
If you look at the chart on post 23 you can see part of the picture. But if you search for solar cycles you can find longer term examples that show how the peaks of the “highs” have decreased over time. I imagine this cycle will peak between 50 and 75 or so. And also be shorter than the last one.
