So I've done a couple of big nordles, and while it's mildly diverting, as long as you get the first couple in 3 or 4 goes the rest is just going through the motions of filling out whichever has the most letters. Not really much working out needed.
Nordle N=80 was no harder than N=40 or 24.
As you say, nail the first few and it's just going through the motions from then. Infact 80 is probably easier to finish as there's there's little or no guessing required, just scrolling up n down.
