Why is the late night (starting backload at around 10pm) providing you can get carbs in until like 1am and then go to bed and wake up next day at around 9?
Late night is bad assuming you don't have time to get carbs in. If you are staying up late and can get carbs in its not really different then the optimal time.
Great, Awesome! I usually try to keep the window of carb loading to 2:30hs max, getting 2 meals in, since im doing SA.
