★ = ties his personal best for this club (same swing as reports #3 and #4). The apex label on the screen is partly hidden by glare; it was read by its slot position and the ft unit. The curve arrow is small, so its direction follows the logbook entry. Club speed and spin aren't on the screen: at a typical iron smash of ~1.38–1.40, 107 mph of ball speed means about 76–78 mph of club speed, right at the LPGA average (78 mph). The ball could not be tracked in the video (30 fps: it is gone between two frames after impact), so its start direction is unknown. Slow motion at 120 or 240 fps would fix that.

What it means: the ball speed is close to the LPGA average and the flight is high and steep, with a 27-yard peak and a 44° landing. The 6-yard carry gap to the LPGA is mostly speed. The 20° launch is 3° above the LPGA and 6° above the PGA Tour, which suggests a little extra dynamic loft at impact. Spin isn't shown, so that is an inference from launch and apex.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. The backswing starts at frame 99 (8.30 s), the top is at frame 117 (8.90 s), and impact is at frame 124 (about 9.13 s).

Tour figure: John Novosel, Tour Tempo. Reports #3 and #4 used this same swing, so they are not listed again. One frame either way moves the ratio by roughly 0.2–0.4.

What it means: 2.6:1 sits inside the good band (2.5–3.5:1) and is the closest he has come to the 3:1 tour pattern with this club. The backswing (0.60 s) is slower than his earlier 6-iron swings. The downswing (0.23 s) is a touch quicker than the tour's 0.27 s, which is fine.

4 The reference frame — how this swing was measured

• Scale: the grid is scaled from his body size in the frame (his height wasn't given), at 10.23 px per inch. Each square is about 5 inches, so treat distances as ±1 inch.
• Center lines: a vertical line runs through the centre of his stance and a horizontal line through the ball line. Both cross at the belt buckle at address and act as fixed references for balance, spine and height.
• Diagonals and depth rays: the two corner-to-corner diagonals add a fixed perspective scaffold. The depth rays are the mat edges and the stick at his feet, extended to the horizon. Anything moving along them is moving toward the target (into the picture), not sideways.
• Address references: the white line is the top of the cap (head height) and the dashed waist line marks waist height. The dashed light-blue lines mark shoulder and knee height. The dashed red tush line is the back of the hips at address. The red trail is the head path and the yellow trail is the hands' path.
• Body measures: head height and waist height changes, shoulder and hip rotation, and X-factor (shoulder turn minus hip turn at the top). Rotation is a visual estimate of about ±10–15°.
• Tracking: body points were tracked automatically on all 210 frames (5.0–12.0 s) and checked by eye at each key position. The camera stayed still: the background moved less than 0.2 px (median).

5 Swing sequence

Nine key positions, filmed down-the-line from behind the hands. The target is straight into the picture.

Photos are numbered in the order they happen in the swing. The frames follow the standard swing positions.

6 Position-by-position biomechanics

Club check

Club check (video at 15.5–18.0 s): the sole shows a digit with a closed loop at the bottom and a small bar beneath it, which reads as a 6 and not an inverted 9. The ball data (146 carry, 150 total) also matches his 6-iron best. Logged as the 6-Iron.

Photo 1 — Address Good

• Upright, relaxed posture with the knees flexed and the arms hanging, hands low and ahead of the clubhead.
• Ball sits just inside the target-line stick, with the diagonal stick marking the foot line.
• This frame sets every reference: cap line, waist line, tush line and belt-buckle crossing.

Photo 2 — Takeaway Head sinks

• The head is already ~4.6 in lower and ~2.6 in toward the ball line. This is where the dip begins.
• The hips move ~1.8 in away from the ball and rise ~1.2 in, so the base stays quiet.
• The hands are ~9.7 in from their address spot, with arms and club leaving together.

Photo 3 — Lead arm parallel Good width

• The hands are ~23 in from the address spot on a wide arc.
• The hips stay ~1.9 in back (no slide toward the ball), while the head is still ~4.6 in lower.

Photo 4 — Top Full turn

• Shoulders turned about 85° and hips about 40°, so the X-factor is about 45° (estimates, ±10–15°).
• The head has come back up to ~2.2 in below address and sits ~2.8 in toward the ball line.
• The hips are ~1.7 in back and ~0.6 in up: they turn, they don't slide in.

Photo 5 — Arm parallel (down) Head drops again

• The lower body leads the downswing: the hips are ~1.0 in back and back at their address height (0.1 in up).
• The head sinks again, to ~4.1 in lower. It was ~2.2 in at the top.
• The hands are ~26.5 in from the address spot, coming down.

Photo 6 — Delivery Solid

• The hands are within ~4.6 in of their address spot, with the arms in front of the chest.
• The head is ~5.0 in lower and the hips stay ~0.9 in back.

Photo 7 — Impact Watch the head

• The head is ~5.9 in lower than at address (Fix) but only ~1.5 in toward the ball line (Good).
• The hips stay back (~0.9 in) and the rear of the hips is ~0.4 in inside the tush line: no early extension. The waist is ~1.0 in higher (Watch).
• The hands return to within ~0.6 in of address. The hips are about 35° open and the shoulders about 20° open, so the hips lead.

Photo 8 — Release Full extension

• Both arms extend and the chest keeps turning through the strike.
• The head is ~6.8 in lower, so the dip is held through the release. The hands are ~7.8 in from the address spot.

Photo 9 — Finish Excellent

• Tall and balanced, trail foot up on its toe and the club wrapped over the lead shoulder.
• The head rises to about 4.4 in above its address height as he stands up into the finish. Held, as in every report.

Overlay — head at address, top and impact

Depth note: from behind, the head's shift "toward the ball" (about 1.5–3 in) sits partly along the depth rays, so it mixes sideways motion with movement toward the target. One camera can't split the two. A face-on clip of the next swing will settle it (see Limitations).

7 Where the 6-iron sits in the bag

Heads-up: the 6-iron carried only 2 yards more than the 7-iron (146 vs 144) and finished only 3 yards longer in total (150 vs 147). Against the 5-iron the gap is bigger: 13 yards of carry (159 vs 146) with just 1 mph more ball speed. The gaps are uneven, but these are single swings from different days, so a few more balls with each club would confirm the pattern.

10 Limitations & next capture

• One swing is a snapshot. This is the same swing and screen as reports #3 and #4, so it adds new measurements but not new ball data.
• Spin and club speed aren't on the screen, so club speed is estimated and the dynamic loft idea is inferred from launch and apex.
• The ball could not be tracked in the video (30 fps), so its start direction vs the target line is unknown.
• Distances come from a grid scaled to his body in the frame. His real height would make the scale exact.
• From behind, depth (toward the target) mixes with sideways motion. That is what the depth rays flag.

Next capture: (1) the same down-the-line spot filmed in slow motion (120 or 240 fps) so the ball can be followed, (2) a face-on clip at chest height, square to the feet, (3) 3–5 new balls for an average, with the range screen read before the glare hits, and (4) André's height, to lock the grid scale.
