Bugholes on as-cast surfaces are an aesthetic issue, not a performance issue related to strength, durability,
or serviceability. Because they are an aesthetic issue, attempts to evaluate bugholes objectively, with measurements,
are not useful. Measuring bugholes using an evenly divided scale or other instrument can reveal their number,
individual area, and total area as a percentage of a sample area. But there is no scale or instrument for aesthetic
judgments. Thus, matching a mock-up surface with the as-cast surface, although subjective, is a better method for
acceptance of surface appearance.
