That´s easy, line pairs are contrast dependent. As long If the didn´t declare at what contrast value (realistic or promotion?) they measured it´s not worth the paper they print on. For example: Technical Pan has an resolution between 125 l/mm and 320 l/mm between 1.6:1 and 1000:1 And if MP uses foolishly real film, the will measure only the whole chain of processing, with all his uncontrolable influences (film types, chemicals, temperature, light, etc...).
