As I said above the 5:1 safety margin is per bolt. Assuming each bolt alone is holding the entire keel. The justification for this is that when the boat is rolled onto it's side, and being slapped by waves, there is no telling how unequal the forces are going to be applied. It very well may be that just the front bolt will have to briefly hold the entire weight of the keel, plus it's momentum on the boat, even if everything else is in good shape.
