The previous thread clarified that, whereas it is realistic that longbow wieldede by a stronger warrior can do more damage, there is a limit to the damage a bow can inflict without breaking altogeher instead of firing its projectile. I would say the DM is whole for bows, but with a limit of 1/2 the bow damage, rounded down (1d2 for self bow, 1d4 for nomad bow, 1d8 for longbow etc.).
