★ first 5-iron with a proximity reading. Club speed isn't on the screen: at a long-iron smash of ~1.36–1.40, 106 mph means about 76–78 mph. Curve direction read from the brighter arrow (left). LPGA/PGA: classic TrackMan Tour averages (5-iron).

What it means: almost a copy of his October 5-iron (−2 mph, −3 yds), so this is his stable 5-iron: LPGA-level speed, but launched ~5° high and landing ~5° shallow, so it runs. Same speed with ~15° launch should give ~160–162 yds carry and a steeper landing.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. Takeaway starts at ~30.95 s, the club reaches the top at ~31.44 s, and impact is at ~31.75 s.

Tour figure: John Novosel, Tour Tempo. Frames: takeaway 74, top 89, impact 98–99.

What it means: his rhythm is consistent across clubs, quick back and quick down. A slightly longer, smoother backswing (~0.6–0.7 s) would bring the ratio toward 2.5:1 and give the body time to rotate without diving toward the ball.

4 The reference frame — how this swing was measured

• Grid: each square is about 5 inches (~7.5 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 (already gone in this frame).
• Body points were tracked automatically on every frame (180 frames, 28.5–34.5 s), 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. Times are from takeaway.

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

Left: impact close-up (frames 97–100): ball at rest, clubhead at the ball, ball gone. Right: the sole shown to the camera after the swing, a clear "5" with no bar under it (on his clubs only the 6 and 9 have the bar).

6 Position-by-position biomechanics

Club: 5-Iron, read on the sole in the video. Logged as report #2.

Photo 1 — Address Good

• Athletic posture, weight centered, hands just ahead of the ball.
• Ball a little forward of center, a normal 5-iron spot.
• Stable over the ball: the cap moves less than 1½ in in the 2 seconds before takeaway (better than in the 8-iron clips).

Photo 2 — Takeaway Watch

• A connected start, hands and chest together.
• But the cap is already ~3½ in lower after only 0.2 s: the dip starts with the first move.

Photo 3 — Lead arm parallel Watch

• Lead arm parallel at ~0.33 s, wide and on plane.
• The cap is now ~6 in below its address line and moving toward the ball: the biggest early dip of the three swings from this session.

Photo 4 — Top Good

• Full turn, club near parallel at the top (~0.50 s backswing).
• The head rises a little (~3½ in below address) and sits ~4 in toward the ball.
• Hips ~2 in back from the ball: they keep their depth.

Photo 5 — Arm parallel (down) Good

• Hands drop in front of the chest; the lower body leads.
• The head starts working back down into the strike.

Photo 6 — Impact Head down

• Clubhead at the ball at ~31.75 s; one frame later the ball is gone.
• The cap is ~7 in lower than at address and ~1½ in toward the ball.
• Hips back at their address depth (no early extension), ~1 in higher.
• Hands ~2 in ahead of their address spot.

Photo 7 — Ball launched Good

• The ball is already airborne within 1/30 s: solid strike (106 mph ball speed).

Photo 8 — Release Good

• Arms extend toward the target; the chest keeps rotating.
• The head starts to come up only after the ball is gone.

Photo 9 — Finish Excellent

• Full, balanced finish on the lead side, trail toe up, held while he watches the ball.

7 Same session, three clubs

The 5-iron flies ~33 yds past the 8-iron, about 11 yds per club, which is healthy long-iron gapping. Across all three swings the head drop is the common thread: every club launches 4–5° above the LPGA window.

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: head and hip distances are ±1–2 in; the start line can't be tracked.
• Club ID: read directly on the sole ("5"). This head is silver, unlike the black 8-iron, so it may be from a different set.

Confidence: high on ball flight, club ID and tempo; moderate on head and hip distances.
