Question on Improved crit ranged/pierce

[chkm8ter]

Looking for clarification on how these work. Of course Bow is ranged and arrows are pierce. If you have both do they stack when you fire an arrow from a bow? Or does Improved critical pierce only apply to hand held weapons such as rapiers rather than projectiles?

[sigtrent]

Bows are covered by ranged and not pierce. Pierce/Slash/blunt only apply to melee weapons. Thrown weapons have their own category.

So then having Improved Critical Piercing has no effect on Ranged attacks ??
