The answer is: 'The peak white luminance ratio is calculated from the two declared values and is implicitly verified if the two declared values used for its calculation are verified.'
It means that there is no verification tolerance for the ratio, only for its numerator (normal luminance) and denominator (brightest luminance). If the two values are verified, the ratio is implicitly verified.
65% are not a verification tolerance but an Ecodesign criterion that the ratio must meet, if applicable.
