A couple of observations. Generations are not typically 20 years long. If you look at the first three S&H saecula (1435-1746) they average 25.9 years in length. Back at the old site a couple of us extended the cycle back to the mid-9th century (period 851-1435 covering 23 turnings), for which the average length was 25.4 years.
To show an 80 year cycle you need to obtain cyclical data going back several centuries. The data presented in chapter 4 is over too short of a period. I would suggest you employ marital age + 1 as a proxy for maternal age. I believe there is English data going back centuries.
