"an extra pawn sometimes wins and sometimes doesn't"
++ Close to the initial position an extra pawn wins. Of course some endgames with 1, 2, or even 3 extra pawns draw, but close to the initial position the side with the extra pawn can steer clear of those and convert the extra pawn.

"confuse weakly solving with a weak solution"
++ Weakly solving leads to a weak solution.
The point is to hop from the initial position to other drawn positions so as to reach a certain draw: 7-men endgame table base draw, prior 3-fold repetition, or certain draw as judged by both ICCF WC finalists and their engines.
White wins are pitfalls for black, black wins are pitfalls for white.
Optimal play by both sides avoids the pitfalls.
"Blunder rates in the endgame generally increase with increasing think time" ++ Nonsense
"humans get weaker much faster" ++ No, humans are better at long term planning.
That is why the humans play the openings, not their engines in ICCF WC Finals.
That is also why humans agree on draws in positions with not the slightest hope of winning, while engines would stupidly play on until a 3-fold repetition or the 50-moves rule.
Troitsky was better than present engines at KNN vs. KP.
"latest version of SF can't play 5 man chess perfectly"
++ But ICCF Finalist + twin servers 90 million positions/s during average 5 days can play 32 men perfectly. Troitsky analysed KNN vs. KP perfectly without any computer.
