 "why_the_factory_disagreed": "The hole-pattern view is the series drawing: it shows ten holes from 1 to End with pl as a symbol; the 4-position value pl = 7.62 mm is only in the Pattern Properties table, and the copper pad size is not given at all. A reader that counts the drawn holes or invents a pad gets a different land pattern from one that reads the table, which fits the factory's refusal (two readings did not agree). Read from the table, the pattern is unambiguous."
