I've been calorie counting for about 9 months. I log everything as I eat it and stop before I hit my red line limit for the day. But, I have shortcuts I've built into the software I use (fatsecret - and their droid app!).
I realized several months ago that I could put together a 400 calorie dinner with amazing accuracy. I was entering item by item, after cooking, before eating, when I realized that I was almost never off by even 10%. So, I have an entry for a healthy meal of 400 calories. If it's a light meal, 300 calories, I enter it at .75. For a big meal - 500 calories - I'll enter it as 1.25. Every few weeks, I'll double check a meal to make sure that my counts are still "there" and I'm not slopping mentally.
