Yes, I would think it should come close. For example, you would need to get readings at various times of the day (and certainly not in the same day!), a few morning fasting, a few before and 2 hours pp after breakfast and other meals, between meals, before bed, empty stomach, after exercise (if you do that regularly), etc. random readings and then average them. My meter gives me a 14 day average so that part is already done but I haven't been testing myself at random times. And, of course, we have to account for our meters being off accuracy by some percentage.
