There is no point at which your damage per str points gets lowered, it always gets lower. It gets lowered from the very first point you put into it. Damage goes by the square root of str. Papi figured this out a long time ago. You may not notice the reduction at times due to rounding. The 300-350 number is a completely arbitrary number that some have decided is good number to use based on experience.

Auto Damage = (0.158 *(STR)^0.5 + 0.061 * (Ability )^0.5+0.95) * PhysicalDamage + ElementalDamage

Yes that would be a good amount, the higher the numbers go up the lower dmg u will get, always, but u can see that from around 350 it barely changes, sticks to 2 dmg per 5 str with several weapons, maybe at much higher str (idk, 1k+ maybe) u will get even less than 2 dmg.
Im just saying that for a while now ive been getting 2 dmg per 5 str with anc wyrmbone handaxe, i dont know how much would it be with mordy spears.

That's me at the moment
