Trumpy,
The rules over here set a maximum of 10 points (lights or sockets) on any one radial. (you can't mix lights and sockets either. 10A for lighting, 20A for sockets)
Obviously, you're supposed to design the radial's load in such a way as to avoid overloading it too, but they're the maximum numbers allowed by the wiring rules.
