Hamar is right. Plus, you are working to make the hard shots and probably blasting through the easy shots becuase you 'know' you can make them and so you go through them quickly and try to make up for time you feel you are losing on the hard shots. The result is that you do better on the hard shots and the easy shots make you look a little silly when compared back to the hard shots.
