OK.
Mine HS2 from the kickback was only hitting the hole about 2/10 times....From a bit of research it should technically hit it every time (9/10 acceptable).
On the left hand side, remove the plastic which sits above the targets...Just slightly loosen the screws (2 or 3 in total - one hidden by ramp) and remove the nut..
Gently slide plastic out. First, ensure that the post has a rubber on it. It does seem to make a difference. Also you'll see a screw. There is virtually no room for adjustment but mine was always hitting the black post (or yellow on yours if correct). I just tweeked it back to the left a touch, and now getting 10/10 from kickback.
Attached a couple of pics...Second one is exact angle of mine..
