How to distribute the remaining points on bone skills ?

Hi, I have summoner necro and I need to spent remaining points to max bone spirit dmg.

In some guides i have read that I need to spent all remaining points to bone spirit.

But in skills calculator I have better dmg when I put not all 20 points to spirit,

but when I put 10 to spear and 10 to spirit.

What is a right way to put points to have max dmg on spirit?|||you can always use the skill planner for the various permutations for highest bone damage..
