So I've spent the early part of the day deciding the look of the charts/links. They look like this:

I then got sidetracked by a suggestion
@amirm made, which was to add a geometric mean (let's call it geomean for short) to each chart. For fun I also calculated the absolute deviation from the geomean (let's call it a GMAD). It's an indication of how far on average the measured values are from the geomean on either the positive or negative side.
If we say that the dataset is a good representation of what's available on the market and you decide to buy a random piece of hardware, you're likely to fall within the GMAD range. How likely are you to fall within that range, i.e., what's the probability? No idea. That's beyond me to calculate.
Anyway, for DACs the geomean/GMAD for SINAD is 95dB/11dB or 15.8 bits/1.8 bits. It's interesting because it shows the tendency is to be around, but slightly below, 16-bit CD resolution. Which means that it was a good call to base the SINAD charts (at least for DACs) on CD resolution, but also that the industry has moved forward by about 12dB if we're to judge by
@LTig's 83dB SINAD measurement of his 1991
Arcam Black Box 3 Mk1.
