I think the problem with firewire's calculator is they factored the riders age in way too much (that and they don't factor in what type of waves you're going to be riding: summer mush, winter barrels, etc).
for instance, I have way more paddle power now than I did at age 20, yet, all the other factors being the same, firewire's calc exponentially adds liters of volume per year of age. IMO, unless someone is over 50, age shouldn't be factored in at all...if surfing on a somewhat regular basis, a person just gets a stronger/better built chest and shoulders the older they get (up to a certain age, of course). If they're going to factor in age, they need to add some sort of bell curve/algorithm.
