Aha! Your quote there, my friend, is more anecdotal evidence for my based-on-nothing-but-a-hunch theory that nonnies like things that are sour, bitter and/or salty versus sickly sweet.
I don't appear to be a non-secretor, and I eat (and enjoy) far too much sweet stuff. I also mostly dislike bitter, but chocolate is the exception, oh yes!
I've been having a bit of the Lindt Excellence 70% just about daily for years, occasionally straying to other brands, but not for long. I tried their 85% a few years ago and found it tolerable, but not as enjoyable. However lately, it's become even more tolerable and the 70% stuff is tasting positively sweet. So, I think that my "sweet-spot" for enjoyment is now somewhere between 70 and 85% coacoa.
Unfortunately, they don't make a bar with a between percentage. One benefit of the 85% is that I savour longer and eat less of it... it's too easy to get carried away and eat a whole bar of the 70% stuff.
I was at my usual supplier a few months ago and saw the so-called 99% Lindt bar, and tried it just to see. It was more expensive (a lighter bar in the same format box), and seemed to have MORE sugar in it. Unfortunately, I got distracted and don't have the package handy to check ingredients and percentages, but I think there's definitely some kind of marketing shell-game going on with the so-called "99%".
When I look back at the "chocolate" candy that I ate as a kid, I wonder how I survived this long. Cloyingly sweet and stuffed with preservatives and unpronouncable chemicals... eeeeyewwww!
Where I live, the Lindt Excellence bars (70 and 85) cost between $2.49 and $3.49, with Wal-Mart usually on the low end, but not always stocked.
