Will a period of 90 days to 1 year be sufficient for getting enough understanding about the religion in question? Many religions claim that one has to spend many years to become knowledgeable.
Your point is fair. I think the time that people could commit to a controlled experiment would be a limiting factor.
I think it would be interesting if people used the post as a jumping off point to do informal experimentation, and they could take the time they thought it would require. This would not necessarily yield the same precision that a randomized trial would, but as per your point, there may be a tradeoff between external validity (taking the time to really practice the faith) and internal validity (limits on time commitment in the context of a randomized trial to gain causal inference).
