Question about Calories burned with Basal, Lifestyle, etc.

[mormonmike]

My account at Fitday.com says with the 4 main exercises I did today that I burned
Calories Burned Today
source cals % total
Total: 4495
Basal: 2371 53%
Lifestyle: 1437 32%
Activities: 686 15%

So this means I burned at least 4400 Calories? Then do I subtract what my daily caloric intake is , which is 2000 Calories. So I am burning 2400 Calories a day on my workout days? My off days would be around 2200 according to these calculations. You kind of get what I am saying?

So basically I am burning 2200-2400 Calories aday?

I would like a little better explanation on this. Thanks,
