I have some thoughts regarding load times in tournament games:
1. Whether to allow load times or not is a personal decision for the player.
2. If a player uses a load time (one or more), they should provide the opponent with at least the same number of load times if needed.
3. If one player uses 2 more load times than the opponent, they are essentially playing for a draw.
In general, I don't understand why people 'beg' for load times – it's a tournament after all. If you lose, either continue the game with what you have or surrender – that's all there is to it. With the time limit (10 minutes per turn), you can think through all your actions and avoid getting 'angry mobs' on you.
