I agree about it's design but not the testing. Limiting testing to this very constrained operating band is not what differentiates a good derailleur from a great derailleur. There were many RD's that could shift that freewheel equally well (possibly better). Some of those would do very well on much wider range freewheels, as well. This is why the Suntour Cyclone and Shimano Crane began to pull ahead of Campagnolo in performance.
