I used .7 to .9 as a standard with my Pentax photos, it seemed to suit the AA filter in the DS and K10D bodies well, and worked well with the 'average detailing' of the subjects I was shooting. With some of the more recent cameras and my current lenses, with very light to no AA filter, I am often finding I don't use any sharpening at all.
Press the Option (Alt) key when clicking on the radius adjustment and you'll see the effect on the photo as you slide the control from minimum to maximum. That's how I came up with the setting.
