For $N = 19, 23, 25$ the minimum energy per particle are lower than the ones tabulated in the literature. Since the energy is lower than the reported ground state energy, bad convergence is unlikely the issue. It could be bad approximation of the potential? The difference is typically only tens of micro eV, but noticeable.
