Most of the newspapers here in the UK set their "HARD" level just below quads........
The adjectives used for something which may be of interest to you would be (Insane, Nightmare, Unsolvable........).
The "Hard" puzzle which you are referring to is actually the odd one out in this sea of published "Hard" puzzles.
I do agree though that we need more difficult puzzles. This forum has plenty & some of them are grouped according to a level of difficulty that you would not find commonly in newspapers...
