★ = personal best for the 6-iron, compared with report #1 (the only earlier 6-iron with ball data). The curve direction isn't clearly readable on the panel. Club speed isn't on the screen either: at a typical iron smash of ~1.38–1.40, 107 mph of ball speed means about 76–78 mph of club speed, at or just under the LPGA average (78 mph). Flat carry (144) and carry (146) differ by 2 yds, probably an elevation adjustment on the screen.

What it means: The flight is healthy: the apex (27 yds) sits between the two Tour averages, and the launch is 3° lower than in report #1 with 4 mph more ball speed. The carry gap to the LPGA average (6 yds) lines up with the 2 mph speed gap, so it is mostly a speed story. The launch (20°) is still above the LPGA 17.1°, and the 44° landing angle is a little shallower than the LPGA 46°. The ball ran out only 4 yds past its carry.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. Takeaway starts at 8.30 s, the top is at 8.90 s, and impact is at about 9.13 s.

Tour figure: John Novosel, Tour Tempo. One frame either way moves today's ratio between ~2.3:1 and ~3:1.

What it means: Compared with report #2, the backswing got a little longer (0.53 → 0.60 s) and the downswing a little quicker (0.27 → 0.23 s), which lifts the ratio toward 3:1. Both parts are still shorter than the Tour numbers, so the whole swing is on the quick side, but the shape of the rhythm is close.

4 The reference frame — how this swing was measured

• Grid: each square is about 5 inches (roughly 46 px). It's scaled from his body size in the frame (9.22 px per inch), so treat distances as ±1 inch.
• Vertical and horizontal center lines (light green): fixed references for balance, spine and height.
• Two corner diagonals (green): they cross at the frame's center and give a fixed perspective scaffold.
• Depth rays (yellow, dashed): drawn from the vanishing point of the target-line sticks. Anything that moves along these rays is moving toward the target (into the picture), not sideways.
• Address references: the white line is the top of the cap and the light-green line is the back of the head. The red trail is the head path and the yellow trail is the hands' path, frame by frame.
• Body points were tracked automatically on every frame (135 frames, about 7.0–11.5 s), then checked by eye at each key position.

5 Swing sequence

Nine key positions, filmed from behind the golfer (down-the-line view). 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

The sole was shown to the camera at 16.5–19.0 s, after the swing. The digit reads as an upright 6 with a bar underneath (high confidence), the same badge style as report #2. Logged as the 6-Iron. The shot numbers fit this club, but they were not used to decide.

Photo 1 — Address Good

• Tall, athletic set-up: knees flexed, arms hanging, club resting behind the ball on the mat.
• The top of the cap sits on the white address line. That's the reference for every head number below.

Photo 2 — Takeaway Head sinks early

• Hands, arms and club leave together; the hands are already ~17 in from their address spot.
• The head is already ~5 in lower than at address and ~3 in toward the ball side. It's the biggest early sink of the swing.
• Hips turn ~2 in away from the ball.

Photo 3 — Lead arm parallel Good width

• Wide arc: the hands are ~31 in from address and still travelling on a smooth path.
• The base stays quiet: hips move only ~2 in away from the ball and ~1 in up.

Photo 4 — Top Head recovers

• Hands high, club pointing up; the hands are ~43 in from their address spot.
• The head has come back up: only ~2.6 in lower than at address (it was ~5 in a few frames earlier), and ~3 in toward the ball side (see depth note).
• Hips are ~2 in away from the ball. They turn, they don't slide in.

Photo 5 — Arm parallel (down) Head sinks again

• The lower body leads: hips move ~1 in back toward the ball and return to address height (0 in up).
• The hands drop inside the line they went up on (yellow trail), but the head is ~4.4 in lower again.

Photo 6 — Delivery Solid

• Hands are within ~5 in of their address spot, arms in front of the chest, club trailing low behind the hands.
• Hips still ~1 in away from the ball, so the body is staying back and turning.

Photo 7 — Impact Watch the head

• Hands return to their address spot (within ~0.5 in).
• Head is ~6.5 in lower than at address, deeper than the ~5 in in report #2.
• Hips hold their depth (~1 in away from the ball) and rise less than 1 in. No early extension, again.

Photo 8 — Release Clean release

• Arms extend toward the target; the hands are ~10 in past their address spot.
• The ball has already left the mat. The head is at its lowest point of the swing here (~7.6 in) and still looking at the strike area.

Photo 9 — Finish Excellent

• Tall and balanced on the lead leg, trail foot up on its toe, belt buckle to the target.
• The head rises ~5 in above its address height and the hips move ~4 in toward the target: a full, free finish.

Overlay — head at address, top and impact

Depth note: from behind, the head's ~3 in shift toward the ball side sits partly along the depth rays, so it's a mix of "toward the ball" and "toward the target", and one camera can't split the two. A face-on clip of the next swing will settle it (see next capture).

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), with 3 mph more ball speed (107 vs 104), and the totals are 3 yards apart (150 vs 147). The gap above is much bigger: 13 yards of carry (159 vs 146) and 19 in total (169 vs 150) to the 5-iron. These are single reports, so a few more swings per club will show the true spacing.

10 Limitations & next capture

• One swing is a snapshot. The range screen appears at 22.5 s, about 13 s after impact (9.13 s), so the readout is assumed to be this swing's ball.
• Spin and club speed aren't on the screen, so club speed is estimated (smash ~1.38–1.40) and there is no spin comparison with the Tour averages.
• 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's what the depth rays flag. The curve direction isn't readable on the screen.
• The file info labeled this angle face-on, but the frames look like a view from behind, so it's treated that way here. A face-on clip would settle it.

Next capture: Next capture, to sharpen the reference frame: (1) the same spot behind the golfer, plus (2) a face-on clip at chest height, square to the feet stick, (3) 3–5 balls for an average, with the range screen in view right after each shot, and (4) André's height, to lock the grid scale.
