Seems to me personal attacks are flying back and forth really. I am one who believes that Rowuk would benefit from a "longer fuse" especially with those who disagree with him. However, I fail to see how the above comment answers the question quoted in the comment in any way. Where indeed are all the players benefitting from Local's system or whatever he wants to call it? I would add that, like Dave, I am not swayed by those who call others' work "old wives tales" then advertise their own view as better without providing better substantiation. However, unlike Dave, I believe that it does matter if one has a coherent system that can be explained in such a way that it allows it to be transmitted to most students with consistent results. That would indeed prove the validity of the system and its formulation to the extent that it makes the results reproducible by many. That actually would be quite an achievement.
