Yes, the movement is controlled by a computer, so a fancy scrambling movement is desirable in order to create meaningful overall results. This of course, is not something that can be done with live players except in a small field Howell movement. However, I believe that the efforts here are trying to bite off more than needs to be chewed. I remember reading an article on switching directon for a few pairs for only 2 rounds of the tourney. The analysis showed that this dramatically improved the overall comparison so that an overall winner could be determined. The movement is simple enough that with a bit of learning, it could be done with a live field. I will post more details when I find the article. With the aid of the computer, the movement can be a little more advanced. Something like each round, 2 pairs change direction. Or even (Number players)/(Rounds of play-1) switch each round. Then almost everyone will have one round in the other direction. Eg, 50 players, 16 boards in 8 rounds. N=50, R=8. (50_/(8-1)=7 players each round. First round, no switching, in the next 7 rounds, 49 players will switch direction for 1 round. Simple and very effective. cheers,
