The two test conditions, in order of increasing theoretical complexity, are: (1) a single test flat covering only a portion of the full-system aperture, and (2) multiple (not necessarily coherent) test flats. Analyses predict limited utility of a single test subaperture as a function of a subaperture size and location, and aberration content.

4D D = maximum test aperture dimension From the viewpoint of suppressing range surface reflections, it is also desirable to maintain the test height H, greater than or equal to 6D. If one must, for practical reasons, employ test heights less than approximately 4D, the …
The screen aperture required has to be decided according to the size of particles in the formation (see below). Because of unavoidable partial blocking of the screen by sand particles, the effective area of a screen is usually estimated at less than half its initial open area. The water entry velocity through the apertures needs to be limited ...
The test method was developed for pavement and subgrade improvement calibrated design methods requiring input of aperture stability modulus. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

When out doing non-lens-test photography, I adjust my aperture in full stops to simplify the exposure math for me. I do the same for lens testing. If you adjust your aperture in half stops or third stops, you will get two or three times the number of test images to sift through and that might be enough to make this process less fun.
