I believe the 25 minute concept is for kids to play continuously for 25 minutes at some point in the game. They may play more, but they should get at least that one, long uninterrupted stretch.
As for game lengths, 12 game season at 50 minutes a game (two 25 minute halves) is only 10 hours of game time. That’s at 7v7 level, not much different.
At 9v9, the point is more valid.
But, for regular season games, which many coaches and TDs view as scrimmages to assess training, which format do you see serves that purpose better? One regulation length game or two abbreviated games?
I don’t know which is better from a development standpoint, it for parents more interested in keeping score, I know which they prefer.
