Definition of metering: To measure a certain volume in cubic centimeters, of powder, intended to weigh x (target); actual weight = y. Variance z = x - y
From best-to-worst metering:
1. Measured and weighed charge y = x. Variance z = 0.
2. Measured and weighed charge y NE x. Variance absolute value GT Zero.
A good metering powder consistently will have a low or Zero variance.
A bad metering powder will have a variance. The higher the variance. the worse the metering.
Thus "metering" is a measure consistency. Varget does not meter well = inconsistent weights from a powder measure.
