I hope you manage to pull down this study before it becomes a witless. It is better to not become a witless in the first place, and easier to leave before committing.
Unfortunately, there is so much pressure to commit before one is ready within the witlesses. In reality, one is ready to commit when they know all the facts about what they are renouncing, realize it is all rubbish, and what the rules are going to be. It isn't necessary to know everything (learning is an ongoing process), but there should be no hold cards in the hand of the religion before committing. Usually they are not fully aware of what is really going on, or they are given bad information to go by. The no cross referencing rule makes it even harder--you could find out that you are going to renounce your life, and everything worthwhile, only after you have committed.
