MikeCFT's advice column

It seems to me that every other question on advicenators is about exercise, so I've made a web page that calculates a simple fitness plan. Here it is:
http://www.geocities.com.nyud.net:8080/theymos/test.html
I have a few questions, to make it accurate:
-Do you think I should add or remove anything from my calculator?
-What percentage of total calories burned should be burned through exercise? The formula I use is:

((current_weight-target_weight)*100)/days_exercising
I also make sure it's below intake(should I do that?).

-Is 21.7(the average normal BMI) the best BMI to shoot for?
-My current formula for "new consumption" aims to get intake to 2600 calories. It is:

calorie_intake-(((current_weight-target_weight)*2)*10)

I also change it to 2600 if it would be below 2600. Do you think that formula if accurate? If not, how should I change it?

Thanks for your help!

Not too bad. I just put in some random figures and will tell you that 2 mins of jogging, 3 mins of biking and 5 minutes of brisk walking isn't enough for anyone.

I never go by BMI at all- it doesn't take into account how much muscle weight there is. When assessing progress I use skinfold measurements mainly and a scale just to keep track with numbers.

Calculators and all make people slaves to scales and calorie counting which is counterproductive. Add in weight training to the list of activities and take out slow walking- doesn't matter whether its fast or slow; the same amount of calories are burned in the same distance.
