1) What determines the amount of each type of raw material needed to repair an entity?

2) Will the raw materials exceed the amounts of each type originally needed to construct or produce an entity?

The RM requirement on the rules page for the entity.

And yes it can go over the amount if you are really unlucky but it should stay with in reason.

Q 1) What determines the amount of each type of raw material needed to repair an entity?

A

“The RM requirement on the rules page for the entity. ”

Yes, I understand that, but; "What determines the amount of each type of raw material..."

Q 2) Will the raw materials exceed the amounts of each type originally needed to construct or produce an entity?

A

“And yes it can go over the amount if you are really unlucky but it should stay with in reason.. ”

How does luck fit into it? And is three times a particular type of RM with in reason?

It goes by % of hull needing repaired times the total amount then it splits that up into steps. Luck plays in because of the Stochastic rounding. So if your luck is bad then it would round ever step up which then would end up spending a lot more than usual
