Eliezer, MacKay actually does predict what we have observed in the simulations. Specifically equation 28 predicts it if you let δf=f instead of δf=f-1/2. You need to make that change to the equation because in your simulation with Beneficial=0, mutations only flips 1 bits to 0, whereas in MacKay’s model mutations also flip 0 bits to 1 with equal probability.
