I did not, but I was only focusing on the next year anyway. It's just something to take into account losing customers. If I take a pessimistic churn rate and it goes down over time I'll be better off. I haven't read the linked post, will do. I don't think I have nearly enough data to know customer lifetime though. I only have 4 months worth of data.
