If 95% of cartridges with 20ml of ink will only allow 18ml to be consumed, is the 20ml an honest figure?
Related to the above, and possibly specifically because of the above, I've noticed that HP doesn't document ink quantity in cartridges, only approximate cartridge yield in pages.
Oh, and the other thing that drives me batty. Their XL high yield cartridges are sold with "Get up to 2x the pages", but from page count it's clear that it contains 1.5x the amount of ink. So ya, you could get 2x the pages, but only if your pages use less ink. There's a disclaimer, but the link is broken.
This is one of those ideas that seems obvious at first glance ... and then problematic with more thought. Have you ever gotten 100% of the peanut butter out of a jar? I haven't. Is that fraud? There's a distinction to be made between jars of peanut butter and ink cartridges, but it wouldn't be easy to draw that line. (For an even better example, see Merchant of Venice, Act 4, Scene 1 ...)

Peanut butter? No. I've gotten really close to 100% out of most containers of liquid though.
The exact location of the line between them might be hard to pin down, but when comparing things as dissimilar as that, it's a great big fat line so the overlap of where you put it and where it should be is probably pretty large, making it easy to place with some confidence.
