For me, cut induced throw (CIT) is responsible for more misses than anything else. I often won't account for enough CIT when I aim a shot which cause me to hit the shot too full and miss.
Anytime I make a mental note to over-cut my shots to counteract the CIT my potting percentage goes way up. But then, after a while, I'll subconsciously go back to my old habits and start missing again. It's a continuous cycle of ups and downs.
I've noticed it really helps to play with dirty balls on my home table. As much as it sucks, it really forces me to think about how much the balls will stick on each shot since the CIT is amplified.
Anyways, I just wanted to share and get you thinking about the factor that is most attributed to your misses as well. Feel free to share your own analysis.
It has been helping me to cut thin shots with a very very loose cradle. No gripping allowed.
