Apparently the GDP per capita in 1950 was 10 079€ for the FRG and 7 886€ for the GDR (78% of the FRG's) and in 1989, 30 035€ for the GDR vs 39 124€ for the FRG (76,7% of the FRG's) - and when the stagnation started in 1981 (possible cause: political turmoil in Poland, just across the eastern border; computer boom in the west; stagnation in the USSR) the gap was at 80,9%.
It did, by about 2,5 years.
