Hi,
This is what they mean. Parsimonious means frugal. In other words , a small ( frugal) scattering of copper in the breast. Not enough to be visually or genetically objectionable. Less than 10% . All of these things go into interpreting the word "Parsimonious" as applied to copper feathering in the breast of the BCM.
