Well, most people want to start off trying a frequency pattern (like abstain) with the one attempt but you don't have to. you could do regular release (protected) + one attempt, or BD unprotected every 4 days (like you describe above) or just let him "do what he does" plus one attempt. The one attempt is the part that seems to work. :)
