Looking at pictures on their site, the holes in the crank can get pretty close to the edge. But, I suppose the load is along the radial edges of the holes so less of a risk of chipping the super thin wall of the crank and ingesting metal.

Thanks and I had no CLUE of how insanely complicated the process really was until we got into it.

Keep in mind the whole come from a template provided by the crank hub source.. in my case, the holes are very tight to the inside rather than on the outside like the shot you shared.
