I don't quite get this.
On a typical Fender style bridge, the bridge saddles are separate for each string and should be flat not radiused. Any 'radius' of the strings, which I take to mean the varied string height above the fret at the octave position, is then brought about by raising or lowering the bridge saddles individually to get the desired action.
Myself, I tend to follow the [url="https://www.youtube.com/watch?v=cIzV9462xeE"]Lakland setup guide[/url] - which gives five/sixty-fourths (G string), five&quarter/sixty-fourths (D string), five&half/sixty-fourths (A string), five&three-quarter/sixty-fourths (E string) as 'medium-low' string heights. If, after setting the neck relief, the bridge saddles are adjusted to those string distances (or similar) then the strings will roughly follow the radius of the fingerboard but it's not achieved by radiussing the bridge saddles - which ought to remain flat but be set at appropriate heights for the desired string action at the twelfth fret.
In millimetres that's roughly 2mm - 2.1mm - 2.2mm - 2.3mm
