Funny.
Matefish is designed to solve 'Mate in x' problems, not 'Mated in x' ...

So the game should end at the 56th black move if we consider correct the line up to 45.- ..., Rxa3. This is, a checkmate in 24 moves (three shorter than The Huntsman 1) with the big 'if' of the first moves.

SF 15.1 disagrees with the other analysis by The Huntsman 1 from 46.- ..., h3 (I can not say anything about the previous moves, as before): while 47.- Nc4 is regarded as the best move by both engines:

47.- ..., Rxc2 would end the game at the 60th black move while 47.- ..., Rg1 would end the game at the 57th black move. Once again, with the big 'if' of the first moves.

Think so too, Jesus, even it will be difficult to prove.
So once again question remains, what's to be called an "easy mate position" and which one engine "solves" that with which one DTM
