That has been my experience and that of my friends/rivals. Campy was designed for racing, and the usual freewheels were a pretty tight range. If you were running an 11 - 24 5 spd. a Campy NR would be great and fast-shifting with it's tight, short cage design. While it could handle a 28 if it had to, it was "happier" not. One would generally go find a derailleur that was designed for the wider ranges. Like Huret, Simplex, and, finally, Suntour. The Suntour Honor really took off and the field of rear derailleurs was forever changed.
