What shot do you practice to test your stroke? Something that should have a high success rate. I was practicing with object ball center table and cue ball almost in the corner pocket. Pretty straight and long. Just not sure what the success rate should be, plus prefer to shoot with hand on the table and not the rail. Although I do like to practice off the rail shots. Just not sure if it's best to test a stroke. I know hitting the bottom rail and having the cue ball come back and hit the tip is one. Prefer to add an object ball but also prefer what's best.
