Spread combines method uncertainty (~18%) and grid resolution (~8/N).

MIL-HS method: MIL fabric eigenvalues give anisotropy ratios · HS+ bound gives isotropic stiffness ceiling from ρ · directional E_i = E_HS+ × normalized MIL weight · surface complexity = SA/V normalized to [0,1] · bell curves show combined uncertainty.
