thanks for the quick answer. There is still another open question.
Currently i am using the exponential churn model for which i can chose a churn factor < 0.5.
Why doesnt it work with a factor > 0.5? (actually i just tested 0.6, 0.7, 0.8)
And if i may ask a second question:
could you give me a short hint on which classes i have to focus to implement the ‘churn feature’ i was asking for?
