The operator monitors the load in the mill and the power and evaluates how they are performing together. They should trend the same. If you have more or less load in the mill, then you should be using more or less power (if the hardness of the ore is the same). If the trends diverge, then something has changed.

Cutoff grade - Wikipedia

Cutoff grade. Cutoff grade is the minimum grade required in order for a mineral or metal to be economically mined (or processed). Material found to be above this grade is considered to be ore, while material below this grade is considered to be waste. [1] The cutoff grade can be determined through a variety of methods, each of varying complexity.
