What weight ratio per day would be for normal use for each item. Say for 4 days, three meals plus two snacks per day, what calorie per day is this good for. At 25% of body weight say at 84 kilos to pounds would be 185 lbs. but at 25 kilos that comes to about 50 lbs. Perhaps the military consider a 3500 calorie a day?? do they include water weight of 3 kilo (7lbs)in that number. how about tarp/blanket, or even a rifle
