Qua differentiatie heb ik hier niets op aan te merken d=1 en D=1 is volgens mij de juiste keuze. Maar ik heb echter wel een andere kleine opmerking. De eerste methode die je toepaste was de VRM-methode en daaruit bleek dat er een goede transformatie mogelijk was met als uitkomst een lambda ban -0,7. Je kon dus evengoed in deze calculator de lambda instellen op -0,7. Ik heb dit voor jouw gedaan en bekom dan onderstaande geblogde uitkomst:

Ik bedoelde de SDM methode in plaats van de VRM methode
