If you eat in the middle of the range, for example, on a non exercise day and the middle of your range on an exercise day (higher calories) it will still equal out to the same deficit at the end of the week had you eaten the same calorie intake every day.
If my basal metabolic rate + activity is 1800 cals. I do not exercise that day and am given a range of 1200-1550 cals. I eat 1400 cals and have a deficit of -400 cals for that day.
If I exercise and burn 300 cals with BMR + activity my calorie needs for the day are 2300 cals. Spark should give me a range of 1700-2050 cals. If I eat 1900 cals I am still creating a deficit of -400 cals because my calorie needs are higher this day.
So instead of having some days with a -800 cal deficit and some days with a -200 cal deficit, you have a more consistent daily calorie deficit. It still equals out to the same weekly deficit had you eaten the same amount of calories every day.
Hope this makes sense.

Take your focus off the Marshmallow. www.leangains.com/2010/01/marshmallo
"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. If you don't want to get bulky, lift heavy!
I can bench Nicole Richie, eat more than she does in a day before noon, I have a good 20 lbs on her but could still wear her pants.
