> What I think is wrong in your argument is that you talk about gain and loose. You bring in the new body weight as if it is added the second you start your trip. It's not. A friend of mine weights in at 90 kg. I am a little over 60 kg. In our normal days he carries 30 kg (66lbs) extra but his muscles are trained for that. If I take a pack with 30 kg it is damn heavy for me.
> Of course there is a upper limit to that idea. And we are both fit and active, so his extra weight is not only fat.

>> I agree, it's not, or shouldn't be, a strict rule.  My application is this: Take your height, and find the "normal" weight for that gender, height and age.  The 25% should be based on that weight.  Say that weight for you is 160 pounds, then your max pack weight is 25% x 160 or 40 pounds.  But say that you actually weigh 170 pounds.  Then you're already carrying 10 pounds of "excess" weight, so I would subtract that from your max pack weight to get 30 pounds.
>> Otherwise, the logical conclusion of mis-applying the rule would be to gain weight to get your pack weight up.  Taking our 160 normal weight hiker. He/she wants to carry 50 pounds.  So in order to make the math work, he would need to get his weight up to 200 pounds yielding 25% time 200 is 50. Ta da!  Obviously NOT what you want to do!
