Yet what happens when these factors aren't? It really matters which individuals fill the slots.

If there are three physically fit and well-trained officials working, then that system will work well. However, if one of the crew members is unfit or lacking in proper knowledge of rules, positioning, or judgment then this will cause a real mess. The other two partners will be depending upon this person to handle his coverage area and when he doesn't, the call will be missed or made incorrectly.
In fact, if there aren't enough quality officials to staff the 3-person system for the games in a league or area, then 2-person with two quality individuals will actually provide a better result.
There is no question that objectively the 3-person system is theoretically better, but the subjective factors will play a much larger role in determining the quality of the outcome in real world practice.

True, but you can't get to the better product of a 3-man game without some growing pains. Do it now, and your better product will be there in two or three years. Wait longer, and the entire process is delayed.
