307 shots · 4 sessions

Your overall form is solid: the foundation is already stable, but performance dips on long shots, higher-difficulty positions, and some half-ball cuts.

Form Snapshot
Overall accuracy is 80.7% at a pace of 4.1 shots per minute. Short-range shots are your strongest area: 260 attempts at 82.7%. Mid-range accuracy is lower, and long shots are still unstable: 5 attempts at 40%, so this is an early signal rather than a firm conclusion.
Data Confidence
This report is based on 307 shots across 4 sessions. Regular playing shots are well represented. Long shots are still under-sampled, while hard strokes, straight shots, and half-ball cuts have enough volume for a useful read.
Session Flow
The session trend shows a calm build-up into form: 78.6% early, 80.6% in the middle, and 82.8% late. That is a good mental sign: performance does not fade toward the finish.
What Holds Up Well
Short-range foundation and medium pace are reliable. Half-ball cuts go in regularly in simpler layouts when pace stays controlled and the stroke does not add unnecessary spin.
Main Leaks
Performance dips on long-range shots, higher-difficulty positions, and some half-ball cuts. Soft pace also sits slightly below the overall standard, which can point to deceleration through the cue ball.
Next Session Plan
Play 5 sets of 6 long straight shots, 4 sets of 10 half-ball cuts, and 30 soft-speed shots with a pause at the top of the backswing. Targets are clear, measurable, and tied to the leaks found in the data.
Shot examples
Video fragments are linked to report conclusions, so feedback can be checked against real shots.
