As I mentioned on this thread or another, what sometimes leads to confusion (and frustration) is the way that the terms "sharpness" and resolution are used interchangeably on these forums. In photography, they mean something different from each other, and I posted a link to those definitions.
"Sharpness" is the clarity and quality of the image the eye sees, in this case looking through a bin, which is more inclusive than resolution and includes characteristics such as apparent contrast, flaring, color saturation, aberrations, distortions, and even distortions and imperfections in your own eyes, IOW, the "big picture". Whereas resolution is a precise measurement of the bin's ability to distinguish fine details, usually tested with a booster and a resolution chart.
