★ first 8-iron report, so these set the baseline. Club speed isn't on the screen: at a typical 8-iron smash of ~1.36–1.38, 93.5 mph of ball speed means about 68–69 mph. The curve direction isn't readable on the panel (both arrows look the same in the glare), so only its size is logged.

What it means: launch is high and ball speed is ~5 mph under the LPGA average, so the ball climbs, lands at 43° and stops fast (3 yds of roll). With the hands a little more ahead (launch ~18°) and the same swing speed, a realistic target is ~128–130 yds carry, right at the LPGA 8-iron.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. Takeaway starts at ~30.15 s, the hands peak at ~30.58 s, the club reaches the top at ~30.65 s, and impact is at ~30.93 s.

Tour figure: John Novosel, Tour Tempo.

What it means: the downswing speed is tour-like (0.28 s); the backswing is short and quick, as in all his irons. A slightly fuller, slower backswing (~0.6 s) would bring the ratio toward 2.5:1 and give the arms time to get the hands ahead at impact.

4 The reference frame — how this swing was measured

• Grid: each square is about 5 inches (~7 px per inch at the golfer), scaled from his hip-to-ankle length, so treat distances as ±1–2 inches.
• Vertical center line (light green): the head's address position. Horizontal lines: cap height (white) and hip height (light green) at address. The white box is the head at address.
• Two corner diagonals (green): a fixed perspective scaffold for depth.
• Paths: the red trail is the head and the yellow trail is the hands, frame by frame from address to impact. The red circle is the ball's address spot. In this frame (one after impact) the ball is already in the air, at hip height to the right.
• Body points were tracked automatically on every frame (210 frames, 28.5–35.5 s), and head height was measured from the top of the cap, then checked by eye at each key position. The camera is fixed.

5 Swing sequence

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

Photos are numbered in the order they happen in the swing.

Impact close-up: ball at rest (72), clubhead arriving at the ball (73), ball gone (74–75).

6 Position-by-position biomechanics

Club: 8-Iron, as named by André. Logged as report #1.

Photo 1 — Address Good

• Athletic posture, weight centered, hands just ahead of the clubhead.
• Ball a touch forward of center, a normal 8-iron spot.
• He settles into the address gradually: the cap sinks about 3 in during the final second before takeaway.

Photo 2 — Takeaway Good

• A connected start: hands, arms and chest move away together.
• The head is already ~5 in lower than when he first set up and still sinking.

Photo 3 — Lead arm parallel Watch

• Wide lead arm, club swinging up on plane.
• The cap is now ~5–6 in below its address line: the dip happens early, the same pattern as his 9-iron and 6-iron.

Photo 4 — Top Good

• Full shoulder turn, club near parallel at the top (~0.50 s backswing).
• The head is ~3 in down and ~3½ in toward the ball versus address.
• Hips keep their depth: no slide toward the ball.

Photo 5 — Arm parallel (down) Good

• Hands drop in front of the chest as the lower body leads.
• The head is already working back down toward the ball line.

Photo 6 — Impact Head down

• Clubhead at the ball at ~30.93 s; one frame later the ball is gone.
• The cap is ~6 in lower than at address, horizontally back on its address line.
• Hips hold their depth (no early extension); hands ~2 in ahead of their address spot.

Photo 7 — Ball launched Good

• The ball is already in the air, rising past hip height on a steep line (22° on the screen).
• Airborne within 1/30 s of contact: a clean strike.

Photo 8 — Release Good

• Arms extend toward the target and the chest keeps turning.
• The head starts rising only after the ball is gone.

Photo 9 — Finish Excellent

• Full, balanced finish, belt buckle to the target, trail toe up.
• Held for about 3 seconds while he watches the ball land.

7 Where the 8-iron sits in the bag

The picture is uneven: 22 yds from 7-iron to 8-iron, but only 6 yds from 8-iron to 9-iron and 3 yds to the wedge. The 8-iron's ball speed is only 1.3 mph above the 9-iron's, so today it behaved like a strong 9-iron. Getting the hands ahead (less added loft) should open the 8–9 gap to a healthy ~12 yds.

10 Limitations & next capture

• One swing is a snapshot; the screen readout belongs to this swing (shown right after it).
• Spin and club speed aren't on the screen: club speed is estimated from ball speed.
• One angle, 30 fps, backlit: the golfer is in silhouette, so head and hip distances are ±1–2 in; the start line can't be tracked.
• Club ID: the clubhead held up at the start of the clip is backlit and too small to read the number; the 8-iron comes from André's message and fits the gapping (between his 9- and 7-iron).
• Next capture: the same down-the-line spot works well; if possible show the sole to the camera from closer (about 1 m) and in the shade.

Confidence: high on ball flight (range screen) and tempo (frame by frame), moderate on head and hip distances.
