Golf P1 to P10 swing positions
The P-System breaks the golf swing into ten checkpoints, from address to finish. It is useful because it gives players, coaches and video tools a shared language: instead of saying "your swing looks off", you can say "your shaft is too steep at P6" or "your lead wrist is cupped at P4".
Quick definition: P1 is address. P4 is the top of the backswing. P7 is impact. P10 is the finish. The positions between them describe shaft-parallel and arm-parallel moments that make the swing easier to film and compare.
P1 to P10 at a glance
| Position | Name | What to check | Why it matters |
|---|---|---|---|
| P1 | Address | Posture, grip, ball position, alignment | Sets the geometry for the whole swing |
| P2 | Shaft parallel back | Club parallel to ground, clubhead outside hands | Shows whether the takeaway is on plane |
| P3 | Lead arm parallel back | Lead arm parallel, wrist hinge, trail elbow | Builds the backswing structure |
| P4 | Top of swing | Shoulder turn, hip turn, lead wrist, shaft direction | Controls transition and clubface delivery |
| P5 | Lead arm parallel down | Pressure shift, lag, hip opening | Reveals whether the downswing starts from the body |
| P6 | Shaft parallel down | Shaft plane, hands ahead, trail elbow position | Predicts path, face and strike quality |
| P7 | Impact | Shaft lean, lead wrist, hips open, head behind ball | The ball only cares about this moment |
| P8 | Shaft parallel after impact | Extension, club exit, chest rotation | Shows release pattern and body rotation |
| P9 | Lead arm parallel through | Arm fold, chest facing target, balance | Confirms whether energy moved through the ball |
| P10 | Finish | Balanced pose, weight on lead foot, full rotation | Reveals sequencing and control |
The backswing positions
P1 Address
At P1, check grip, stance width, spine angle, knee flex and ball position. A strong P1 does not guarantee a good shot, but a poor P1 makes every later correction harder. From a down-the-line camera view, your hands should hang naturally under your shoulders and the club should sit squarely behind the ball.
P2 Shaft parallel in the takeaway
P2 happens when the club shaft first becomes parallel to the ground. The common mistake is rolling the hands inside, which pulls the club behind the body and often creates an over-the-top move later. A good P2 keeps the clubhead slightly outside or in line with the hands.
P3 Lead arm parallel
At P3, the lead arm is parallel to the ground and the wrists have begun to set. This is where many players lose width or let the trail elbow fly. If you film your swing, P3 is a great checkpoint for arm structure and club plane.
P4 Top of swing
P4 is the top of the backswing. Look for a stable lower body, full shoulder turn, controlled hip turn and a lead wrist that does not cup excessively. Overswinging past your mobility limit often creates timing problems in transition.
Transition, delivery and impact
P5 Lead arm parallel down
P5 shows how the downswing starts. Better players usually begin shifting pressure and opening the hips before the arms rush down. If your wrists release early here, you are likely casting and losing speed before impact.
P6 Shaft parallel before impact
P6 is one of the most important checkpoints for slice and hook diagnosis. The shaft should be approaching from a playable plane, the hands should be ahead of the clubhead, and the trail elbow should be in front of the trail hip rather than stuck behind the body.
P7 Impact
P7 is the moment of truth. Check shaft lean, lead wrist position, hip rotation, head position and balance. Impact does not need to look identical for every club, but the pattern should match the shot you are trying to hit.
Release and finish
P8 Shaft parallel after impact
P8 shows whether the club releases through the ball or stalls. Good extension after impact usually means the body kept turning and the arms did not collapse too early.
P9 Lead arm parallel through
At P9, the chest should be rotating toward the target and the arms should fold naturally. A cramped P9 can indicate that the body stopped and the hands took over.
P10 Finish
P10 is the balanced finish. Hold it until the ball lands. If you cannot hold the finish, your swing may be out of sequence, too aggressive, or moving away from the target through impact.
How to film P1 to P10 correctly
- Use two camera angles when possible: down-the-line and face-on.
- Set the phone at hand height, not on the ground.
- Keep the whole club and body in frame from P1 to P10.
- Use good light so the club, hands and hips remain visible.
- Record several swings. One swing can lie; a pattern tells the truth.

How SmartCaddie uses the P-System
SmartCaddie uses phone-camera analysis to detect body landmarks and key moments in the swing. The goal is not to replace a coach; it is to make practice more objective. By comparing your P-System checkpoints over time, you can see whether a drill is changing your actual movement instead of only changing your feel.
