Swing AnalysisSwing AnalysisA frame-by-frame review of the 4-iron swing from the October 14 session at Mariners, filmed down-the-line from behind the hands. It is the second 4-iron report, built on the full reference frame (grid, center lines, diagonals, depth rays, cap, waist, shoulder and knee lines), with body rotation, a scorecard and simple next steps. The range-screen photo was too blurred to read, so there is no measured ball flight this time.
Bottom line: a clean, well-organized 4-iron on the movement side. The hands came back to their address spot within ~0.5 in, the hips stayed back (~1.3 in away from the ball at impact, ~0.9 in behind the tush line), and the tempo is 2.7:1 (0.63 s back, 0.23 s down). That sits inside the good band and is much closer to the Tour 3:1 than report #1 (~1.9:1). ★ Personal best for 4-iron tempo ratio. The one constant is still there: the head is ~6 in lower than at address at impact.
There is no measured ball data: the range-screen photo could not be read, and the ball can't be followed at 30 frames per second. For reference only, the app's estimate from report #1 is ~112 mph ball speed, ~170 yds carry and ~187 yds total, all estimated, so no personal best is claimed for distance. The coil is strong too: about 85° of shoulder turn against about 40° of hip turn gives an X-factor of about 45°. The head has already sunk ~5.7 in by the takeaway frame, so the dip starts early in the swing.
Hips stay back, hands return to address within ~0.5 in, and the tempo ratio of 2.7:1 is a best for this club.
The head is ~6 in lower than at address at impact. Keep the cap near its address line so the club bottoms out in the right place.
The head has already dropped ~5.7 in by the takeaway frame. A calmer first move should make the rest of the swing easier to keep tall.
| Metric | Estimate | Range | Source |
|---|---|---|---|
| Club speed | ~81 mph | 77–84 mph | Estimated |
| Ball speed | ~112 mph | 108–117 mph | Estimated |
| Carry | ~170 yds | 164–177 yds | Estimated |
| Total | ~187 yds | 179–194 yds | Estimated |
Not measured: no range screen in this clip. Your 1 earlier 4-Iron report with range-screen data, adjusted by this downswing time (at most ±2%). Confidence: moderate on club speed and yardage, low to moderate on ball speed. Not logged as a personal best.
What it means: A photo of the range screen or a 240 fps slow-motion clip makes these numbers more precise.
30 frames per second, so each time is accurate to about ±0.03 s. The backswing starts at about 48.50 s, the top is at 49.13 s, and impact is at about 49.37 s.
| Group | Backswing | Downswing | Ratio |
|---|---|---|---|
| André (4-Iron #2, Oct 14 session) | ~0.63 s | ~0.23 s | ~2.7:1 |
| André (4-Iron #1, Oct 7) | ~0.50 s | ~0.27 s | ~1.9:1 |
| André (8-Iron #1, Nov 4) | ~1.90 s | ~0.37 s | ~5.2:1 |
| PGA Tour (Tour Tempo, "24/8") | ~0.80 s | ~0.27 s | 3:1 |
Tour figure: John Novosel, Tour Tempo. One frame either way moves this ratio between ~2.2:1 and ~3.3:1. The 8-Iron row is the most recent report of another club and is an outlier, with a very long backswing.
What it means: The backswing grew from ~0.50 s to ~0.63 s while the downswing got quicker (0.27 s to 0.23 s). That is the move toward the Tour 3:1 pattern that report #1 was missing. The 4-iron now sits in the good band.
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.
Opening frames (0.0-1.5 s): the sole of the iron shows a clear 4. Logged as the 4-Iron, high confidence.

| Tempo (back / down) | 0.63 s | 0.23 s | ~1.9:1 (0.50 s / 0.27 s) | Good 2.7:1, band 2.5-3.5:1 |
Depth note: from behind, the head's ~3.6 in shift at the top sits partly along the depth rays, so it mixes "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.
| Report | Session | Tempo | Logged finding |
|---|---|---|---|
| Driver #1 | Oct 7 | ~2:1 (0.5 s / 0.25-0.3 s) | Head dip noted, same as the 4-iron #1 |
| 4-Iron #1 | Oct 7 | ~1.9:1 (0.50 s / 0.27 s) | Same head dip, ~2:1 transition, launch too high |
| 4-Iron #2 | Oct 14 | ~2.7:1 (0.63 s / 0.23 s) | Head ~6 in down at impact; hips stay back |

The link: the head dip is the thread through the earlier reports (driver, then 4-iron #1) and shows up again here at ~6 in. The tempo, by contrast, is changing for the better: from ~1.9:1 to 2.7:1 on this club. Fix the dip and the 4-iron has a very solid base, because the hips and hands already behave. Treat this report as one without ball data.
Confidence: high on tempo and key-frame timing (measured frame by frame); moderate on head and hip distances (grid scaled from body size, ±1 inch); low to moderate on the rotation angles (visual, ±10-15°); low on the toward-ball vs toward-target split (needs a second angle); no measured ball data.
Same camera spot. Keep the top of the cap close to the white address line until the ball is gone, for 10 balls.
Feel: "chest over the ball, knees keep their flex." This targets the ~6 in dip.
Make the takeaway slowly and pause when the hands reach hip height. Check on video that the cap hasn't sunk, then swing through.
The head is already ~5.7 in lower at the takeaway frame, so this is where the dip begins.
Keep the same rhythm that produced 0.63 s back and 0.23 s down. Count "back-2-3, down".
It is the best tempo ratio in his 4-iron logbook.
Back pockets stay near the address tush line through impact, as they did here (~0.9 in behind it).
It protects the base while the head work happens.
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 sharp range-screen photo, held steady and square to the screen, or a screenshot; (3) a face-on clip at chest height; (4) 3-5 balls for an average; and (5) André's height to lock the grid scale.
