Deze opdracht werd correct uitgevoerd. Bijkomende uitleg voor het klein ziekenhuis:

Hier kunnen we vaststellen dat er geen convergentie meer is. Omdat het om 80% gaat zal het veel langer duren om convergentie te verkrijgen. Hiervoor kunnen we de tijd veranderen in bijv. 100 jaar. Maar dit is niet mogelijk om toe te passen in de software.

Correct!
