Using a digital camera to evaluate view camera lenses, not gonna work. Digital image sensors have an entire stack of filters and often micro lenses to aid the image sensor to produce the image data. These solid state image sensors do NOT behave like film.
The only valid way to do any kind of view camera testing is to use them as they have been designed to be used. In the case of Fujinon-A, G-Claron, Symmar-S and countless others, they were and are designed for film, NOT solid state image sensors with a stack of filters and micro lenses in front of the image sensor.. why is this different than film? These image sensor surfaces do not have the same light reflectance- absorbance- responds as film. As for resolution, diffraction for a given lens aperture must be figured in and how might contrast rendition be measured? What about in to out of focus rendition and transition?
As previously posted and mentioned, this previous post comparing scanner to Leica M420 microscope image of 5x7 Ektachrome made using a 14" APO artar decades ago provides some idea as to the optical performance of a process lens on paper has not been made ideal for images at or near infinity.

Working or image taking aperture should depend on image goals, not the idealized lens aperture. Think lens serving your image goals instead of serving the idealized lens design goals.
Having done plenty of these lens test decades ago, not convinced these test are of any generalized value except for checking out a specific lens before ownership acceptance.
