There is no normal. Every beer has it's own schedule and characteristics. 4 days might be a bit soon to rack to secondary, it might be right on. Many times it depends on the gravity of the beer. I'd leave it in secondary for about 3-4 weeks, but that's just me. I have plenty to sip on until that would have time to finish. If you are itchy to get this one going, give it a week or so and check the gravity. If it is the same 3 days apart, bottle it. If not, give it some time and check again. You aren't going to do your beer a disservice by waiting, rushing on the other hand...RDWHAHB
