I think pirates had to do some math when sharing the loot.
But seriously, I don't think there is a problem with trying to optimize the use of the limited amount of skill points we have at our disposal and mathematics is a good tool for that. Besides, real pirates never encountered the concept of hit points... And this is a game, if someone finds it fun analyzing things with math, that's part of their gaming experience. I myself always enjoy a bit of math where it can be found.
To Spaghettimonster:
As for the flourish hitting three times adding to the total damage indicated, I'm pretty sure about that. But if someone else could confirm that, it would be nice, wouldn't want to give false info.
