I have been playing around with different ways of thinking.  Trying to think of what I should do but only thinking of scores and thinking that I need to make it perfect.  Some of my best series come from a relaxed but focused mind.  I am not trying to make it good, I am not trying to think about what I am doing, I am just doing it.

So I  am going to try that for a while again.  Scores dont matter, take the nike motto, just do it.  

The other thing in the make is a firmer grip on the pistol, using the whole hand, even little finger.  This provides a stable pistol, less prone to trigger jerking.  The only problem is if your not focused I tend to pull the trigger with my whole hand, but if I can concentrate, just work that one trigger finger, then even my 4 seconds shooting will be better.
