Acceleration down to which the acceleration can, at best, stay within a fraction δ of the MOND-like acceleration as a function of δ. This is for f_G/m² = 0.99 Mpc². We show the result for both numerical (solid lines) and analytical (dotted lines) solutions and for various baryonic masses M_b. The analytical approximation is shown only where our estimate Eq. (J.36) says that the approximation is better than q = 10%.
