How is damage calculated?

I had only thought of this question recently (after all, I did start playing on my Dual Blade a lot more) but I noticed that when I attack, I deal a strong attack, followed by a weaker attack.

For example, when I use Triple Stab, the first and third attacks deal more damage than the second one. When I use Fatal Blow, every other attack starting with the first deals higher damage while every other attack starting with the second is almost a quarter of the former.

Which leads to me wondering: How is Dual Blade/Katara damage calculated? I always thought that the max Katara damage is the lower number in your damage range, because the maximum damage I can deal with my katara (for example, in Fatal Blow) seems to match with my minimum damage.

Any thoughts?
