I think you are trying to make a really good point. But, I think it is too much. It might be OK for bragging rights, but not for educational purposes. Here is my attempt to steal your idea with a little less.

TRIP LENGTH> six days (W/five nights) - period (This is mainly for fuel calculation)

AO> area of operations and time of year.

Count consumables. I think this is important because this is were a lot of weight can be shaved or added. Sure, the big three are important, but you can have a sub 5lb big 3 and still carry a 50lber.

Count items carried out of pack ie. shoes, clothes worn....

By listing the AO and counting consumables, I think a lot is evened out. Phat might carry more gear in summer to stay warm, but Pika would probably carry more water. It would be interesting to see how it turns out.

Just my take on things. <img src="/forums/images/graemlins/grin.gif" alt="" />
