I ask a similar question.
I put in the shoes of my opponent and ask/ Is winning this position for me just a matter of technique
If the answer is yes, I resign
In general I agree with this article as usual but here I feel like it misses one aspect of not resigning. Being a warrior is important and can help you save dozens of points. The same goes for resigning though. By playing a lost position you spend a lot of time and effort which can be physically and emotionally tiring potentially resulting in losing the next game maybe saving 1/2 from the first game but losing a game you expected to win.
With resigning there are two sides to the coin considering practical play.
My long time rule on this comes in four stages (I am roughly 1950 USCF [pre-covid, I have learned stuff since then] which translates to roughly 1850 FIDE) :
1) At the beginning of the game, regardless of what color I have, I play for the win.
2) As the game goes on and playing for a win becomes too far fetched, then I play to save a draw.
3) When I can no longer find a way to save a draw, I look for a way for my opponent to blow the win and keep playing, keeping in mind time left and opponent's strength.
4) When I can no longer find a way for my opponent to blow the win (same caveats as part 3), then I resign, and I do my best to do so gracefully and not ruin my opponent's joy at winning.
The only real exception to this is when the end is near, and my opponent can mate me in a nice way (i.e. not a mundane checkmate), and then I won't resign and will instead let the mate play out. I take pains to let my opponent know afterwards why I didn't resign so s(he) won't be insulted at my forcing the game to be played to checkmate.
P.S. I have played against some pretty strong youngsters who refused to resign in dead lost positions, and I simply tell myself that a coach somewhere along the line probably told them to "never resign" so instead of getting mad I simply take enough time to make sure I don't move too fast and blunder away my win out of frustration.
