Two questions are graded separately. The rating of a business from a customer’s perspective reflects how it treats gun owners who spend money there. The rating of a business from a supporter’s perspective reflects whether it actively defends the right. A business can score well in one area and poorly in the other.

Evidence ages. An old receipt says less about a company today, so it counts for less. A record too old or too thin to support a letter shows no grade rather than a guess.
