How often do Assault Missiles actually miss

By Hrathen, in X-Wing

I have been thinking of running a green with PTL and an AM, 27 points but means he can get into position, TL, focus, and let loose. Almost tempted to take a second, but only got one of each ship so far.

My daughter has enjoyed this setup and plans on running 2 of these and 2 Red Squadron Xs for AaIA.
