What is the top cross-section of the fourth order of accuracy?

The question is about how the size of the top cross-section relates to achieving a fourth-order level of accuracy. When aiming for fourth-order accuracy in this context, you need enough sampling points across the section to reliably capture changes up to the fourth-degree term. In this practice material, the standard convention for a fourth-order target uses a 20 by 20 cross-section. This size provides the necessary data density to fit the higher-order behavior without unnecessary excess. The other dimensions either provide more points than required or are smaller than what the standard uses, which is why 20 x 20 is the best choice for this item.
