Well, studying the chart and text on that UK site, I'm beginning to see that it's not always black-and-white (except in theory). He points out that there are factors like slop and the designed-in pulley float of the Shimano derailleurs that allow "good enough" match so that the travel/spacing relationship can be mismatched as much as 0.6mm and still be considered a good combo (by him). He also says the "good match" can degrade with wear until that amount of inaccuracy will not be tolerable, too. I'm curious if anybody has experimented with more alterations to the mounting point on Shimano RDs (more that just the rotate tab and re-clamp cable deal he calls the Hubbub): if that changes the ratio from 1:7 to 1:6 maybe something can be devised that goes to 1:5 and1:4 (Campy RD old and new ratios).
Just thinking...
