How long a game of this can last?

I had made short statistical analysis on basis of 65 correspondence games which were played according to International rules, but on 14x14 board. I excluded these games which were drawn on mutual agreement or where one player surrendered before move 60 for more realistic picture.
Average number of moves: 134, median: 139, highest number of moves: 185.

Another video about Capital pool checkers. I believe that this club recently had to close.
