Well for one they did not specify why they change from 1+50 to 1+75, I guess it could be so they could get the same CI and densities. But overall the table shows that Rodinal does as good or better as the others in some areas and not as good in others, just like any developer. Did you actually read the table? seems to me your conclusion as to rodinal's performance is way off. To me it looks like it does just as good as the others. BTW, if you are going by the position in the charts, please notice it is an alphabetical order, not a performance order.
PS, I dont know if you are the same beckert as the one on PN, or if you also are the same as Scarpatti, all I want to say is dont come to this forum and mess it up, I will make your life miserable, ask simmons.
