Centroid points from blocks: number of centroid points used to estimate block effects
Blocks: for each block a centroid run will be added to estimate block effects
Vertices desired: points to estimate the linear mixture terms (minimum of twice the number of components)
Vertices available: maximum number of vertices that can be added to the design
Additional centroid points: points in the exact center used to estimate curvature
Total: sum of vertices desired, and additional center points.
