Look at the score margins here. This is just SL as well. The scores you posted (approx half of them) were also for div 2, and the cups, so there werent many same league blowouts in 1983/84. Contrastingly there were a whopping 21 SL games were the winning team got 50 pts or more! And 7 matches were the winning team got 60 pts or more. Compare that with div 1 results only in 1983/84
