The fort Denison charts show a clear average increase from 1950.
1980’s Av around 6930 mm
1910’s av around 6970 mm (early peak period)
1920 – 1950 – av around 6940 mm
1950 - 1970 av around 6990 mm
1970 to 1990 av around 7020 mm
Early period peak:
1910 – 7020mm (one only before 1950)
Peak from 1970 – 7040mm x 3
We seem to have gone from averages of 6930 mm to 7020 mm.
You can see that rise against Nana's boots in Tony's Manly pictures if you look closely.
