A few points is 2-5, depending on the target gravity. The range can be calculated based on the original gravity and the attenuation range of the yeast. With an expected OG of 1.065 and a TG of 1.010, the attenuation would be 85% (which is really high). So, starting at 1.056, your new TG would be 56(1-.085) or 1.008. Using a more realistic 75%, you'd get 1.014.
Getting 85% attenuation for an extract batch isn't very likely, even with Pacman yeast.
