Pob basic alloy question

[Maddox]

Hi.

Been looking into building a pob and I have a question regarding the amount of basic alloy the consume. In the guide, it says

Base repair rates and damage rates are:
Wear and Tear Damage every 16 seconds = 300 + (base level x 300)
Repair every 16 seconds = base level x number of types of repair commodities x 60,000

It also says

A base that goes unassualted will use 10800 Basic Alloy per 24 hour period to repair the Wear and Tear damage

I may be being a bit dense here, but those two seem to contradict each other. Can someone tell me how much BA each of the core levels need each day.

Cheers.
