If everything entered is correct, your TOTAL calorie expenditure will DECREASE when you enter sleep. It shows the calories in there for sleep, but what it does is replace the higher calories per hour of your daily lifestyle level with the lower calories per hour of sleep, not adding them on top of everything. Go to a blank daily log, like tomorrow. Look at how many calories it has you burning total. Then enter sleep. Look again at the total calories burned. It will be less.
In other words, if you don't enter sleep, you have at the beginning of a day 24 hours of lifestyle calories. If you enter 8 hours of sleep, you have that, plus now only 16 hours of lifestyle calories. Sleep burns less than lifestyle, so the overall effect is a reduction in what is burned.
Many of us feel our numbers are more accurate if we enter sleep as opposed to not doing so.
And now that you don't have to be perfect, you can be good.
