On the screen, the target flag reads 212 yds and the ball marker 199. The curve direction isn't shown on the panel. Club speed isn't on the screen either: at a typical 3-wood smash of ~1.45–1.48, 121 mph of ball speed means about 82–83 mph of club speed, right around the LPGA average (81 mph).

What it means: the launch angle (10°) is right in the tour window, yet the ball peaked 12 yards lower than the LPGA average. Same launch with a much lower peak points to low spin, the classic sign of contact low on the face. With his speed, a normal 27-yard peak would add an estimated 15–20 yards of 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 35.97 s, the top is at 36.47 s, and impact is at about 36.77 s.

Tour figure: John Novosel, Tour Tempo. One frame either way moves the ratio between ~1.6:1 and ~1.9:1.

What it means: the downswing (0.30 s) is in a good range for a long club. The backswing is the short, quick part, so the ratio is the lowest in the logbook. The PW #2 swing already showed he can make a slow backswing.

4 The reference frame — how this swing was measured

• Grid: each square is about 5 inches (48 px). It's scaled from his body size in the frame, 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 two 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 (140 frames, 35.0–39.6 s), then checked by eye at each key position.

5 Swing sequence

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

Photos are numbered in the order they happen in the swing; the names follow the standard swing positions.

6 Position-by-position biomechanics

Club check

Opening frames: a TaylorMade r7 fairway wood, with "3 wood" said on the audio at 0:02. Logged as the 3-Wood.

Photo 1 — Address Good

• Feet parallel to the white feet-line stick; the cross stick marks the ball position.
• Tall, relaxed fairway-wood posture: knees flexed, arms hanging, hands just ahead of the ball.
• Ball on the mat (no tee), the right set-up for a real fairway-wood test.

Photo 2 — Takeaway Good

• One-piece start: hands, arms and club leave together.
• The head has already started to sink about 1 inch on the grid. It's the first sign of the dip.

Photo 3 — Lead arm parallel Good width

• Wide arc, wrists setting on time.
• Trail knee keeps its flex. The base doesn't sway: hips shift less than half a square.

Photo 4 — Top Head dips

• Full shoulder turn, shaft short of parallel, which suits a 3-wood.
• Head about 4 in lower than at address, and ~4 in toward the ball line (see depth note).
• Hips move ~2.5 in away from the ball. That's good: they turn, they don't slide in.

Photo 5 — Arm parallel (down) Good

• Lower body starts the downswing and the wrist angle holds.
• The hands drop inside the line they went up on (yellow trail).

Photo 6 — Delivery Solid

• Club comes from the inside, with the arms in front of the chest.
• Trail heel starting to release, right on time.

Photo 7 — Impact Watch the head

• Hands return to their exact address spot (within half an inch).
• Head is ~5 in lower than at address. Same pattern as every earlier report.
• Hips hold their depth (0 in toward the ball), so no early extension this time. That's better than his irons.

Photo 8 — Release Full extension

• Both arms extend down the line and the chest keeps turning.

Photo 9 — Finish Excellent

• Tall and balanced on the lead leg, trail foot up on its toe, belt buckle to the target.
• Held, as in every report.

Overlay — head at address, top and impact

Depth note: from behind, the head's 4-inch shift 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 section 10).

7 Where the 3-wood sits in the bag

Heads-up: the 3-wood carried only 5 yards more than the 4-iron (172 vs 167), even with 11 mph more ball speed. The difference shows up in the total (200 vs 183) because the low flight rolls out. A normal 3-wood flight would open a 20–25-yard carry gap over the 4-iron. The 3-Hybrid, with no report yet, sits in that gap.

10 Limitations & next capture

• One swing is a snapshot. The ball readout matches this swing, as it's the screen shown right after it.
• Spin and club speed aren't on the screen, so club speed is estimated and low spin is inferred from launch and apex.
• 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 exactly what the depth rays flag.

Next capture, to sharpen the reference frame: (1) the same down-the-line spot, plus (2) a face-on clip at chest height, square to the feet stick, (3) 3–5 balls for an average, and (4) André's height, to lock the grid scale.
