I apologize if this is answered somewhere, but I couldn't find it.
Mining Production Technology: "Annual production of accessibility 1. 0 minerals for each mine or automated mine. Small amounts of lower accessibility minerals will be produced; half annual rate for 0. 5 accessibility, one tenth annual rate for 0. 1 accessibility, etc. "
Do these "small amounts" subtract from the actual Quantity, or are they in addition to it (reducing waste, etc. )?
In other words, if I have 1000 Quantity, then Mine 100, and gain an extra 5 from the current Mining Production Tech, is the Quantity afterwards 900 or 895?
I ask because if the actual Quantity is reduced by these extra minerals and they are produced at a lower accessibility rate than you are losing minerals in the long run, trading total amount for increased mining speed.
