RV3 Rudder Horn

I'm in the process of shaping the rudder horn of the RV3. The drawing call for a radius of 5/16" in each corner. A 1/4 " hole is then drilled at the centre of the radius at each of the corners. By my calculation this only leaves 3/16" edge distance. Why so little? The length of the clevis for the rudder cables is at least 1/2", so the edge distance can be much greater than 3/16". Note that a 3/16" ID bronze insert is use the 1/4" inch hole.

Any comment? Did any do any thing different when locating these holes.
 
Built mine by the plans, but don?t see an issue if you want to slightly increase the edge distance
