We just add another multiplier into the mix which we call BMI. (Body mass index).

You calculate your BMI by taking your height in meters and mulitply it by your weight in 50kg installments (round down).

So:
A human that stands 1.8 meters talls and weighs 70 kg has a BMI of 1.8. (1.8 x 1)

A troll that stands 2.8 meters and weights in at 190 kg has a BMI of 8.4 (2.8 x 3 weight units).

A pixie that stands 51cm tall and has a weight of 20kg has a BMI of 0.51 (0.51 x 1).


Now just multiply the SR carry weights by your BMI and you get your new number.


Now you just have to figure out how much everything weighs.... Is it perfect? Nope. But we find it gives a closer weight to what people can carry based off of our life experiences.

Reaper;
Note: I was going to present this in more detail after I had some time to think and work out some numbers but I thought I would post it in response to your info above.
Please pay attention to the fact that I have to really work up the numbers just thought about a formula.

I was thinking about using just strait mass of race multiplied by 20% and then using that figure as a basis for the basic rules. This is to prevent the over prevalence of fat PC's to up there weight allowance (or fat pixies in your post above).
Right off the top of my head for humans I was going to have weight allowance/encumbrance limit be  mass*(.2+mod)+quality, but  modified if your Body or ST was above/below 3. For above 3 each point of St would give you +2% and body +1%, and if your ST stat was below 3 -4% and ST -2%.
So a human with a body of 1 and ST of 1 would have mass*(.2-.08-.04) = mass* (.08) for weight allowance/encumbrance, and the high of (B=6 ST=6) mass *(.2+.06+.03) = mass * (.29).
But again I need to look at the actual numbers and some real life examples:
Your 70 Kg human with B=6 and ST=6 would have an enc of 20.3 kg (44.75384 pounds) vs the 15 kg (33.0693 pounds) as the book says.
Your 70 Kg human with B=1 and ST=1 would have enc of 6.3 (13.8891 pounds) vs 15 kg of the book.

So for humans where does my formula need to be changed or does it?
  IMHO I really need to look at some real world stuff but if you have different move mods (maybe 1st enc level and 4th enc level)  based on enc levels the B=3 S=3 person would carry approx (33*4) 132  pound pack and the high would be  approx (45*4) 200 lb pack. 
 I think those numbers might need to be adjusted but I do like the idea of using % mods and Kg's as the base as it seem to work a bit better than using the English system.

Also what cyber and or bio should change the formula for humans?
Also should difference core races have different base numbers? ie dwarves use ave mass*.3, trolls ave mass *.4, pixies ave mass* .1, etc

Thanks,
And again it is a work in progress with me having put in just a little thought but not much on the human side of the equation.
