I stagger my calories, mainly to keep my body "guessing". I don't obsess with exact numbers but I stay within the range of 1,300 to 1,700. If I know I'm going to have a real high calorie day or weekend, I'll compensate with a few lower calorie days before or after. My stats flucuate as well. Fat is usually 65-75%, 5-10% carbs and 20-30% protein.
