I haven't had these problems with the end-of-game fouling.
1. Normally, you only get one or two of these strategic fouls before it either works or backfires. After that, the game is usually too close or too far. And, it's a small percentage of games where this is even attempted.
2. I can't recall the last game I had that took an hour and a half, must be a regional thing.
I think you're attempting to solve a problem that is purely philosophical.
