This is an individual thing and is best approached by trial and error. Remember the high radius low Intensity numbers are really meant for items without sharp corners, more like water, hills, faces and also where you have a high amount of noise in your image due to high ISO. Also it is often used in combination, like I did with higher intensity, lower radius sharpening. the 40,7, 4 number came from experiments by Jason O'Dell for capture sharpening with a D700. You have most likely been influenced by numbers you have seen used in Adobe products which are a different scale. Also remember by default CNX2 only sharpens the luminance channel, much like going into LAB in Photoshop. This helps because you are not sharpening color noise.
