André Rennes — 3-Hybrid · Full Swing Analysis

1 Executive summary

Bottom line: a well-timed first 3-hybrid with a stable base. The tempo is 3.0:1 (0.70 s back, 0.23 s down), the same ratio as Tour Tempo. The hips stayed back through impact, with the rear of the hips just 0.4 in from the address tush line. The clip has no range-screen data, so there are no measured ball numbers. From his 11 measured shots with other clubs, the ball speed is estimated at ~117 mph, club speed at ~81 mph and carry at ~165 yds (range ~145-185). Confidence is low. For reference, the LPGA Tour 3-hybrid averages are 123 mph ball speed and 174 yds carry.

The one clear improvement is height. The head sinks about 6.4 in by impact (7.4 in by the release), and the sinking is already there at the takeaway (~5.4 in). The hips also rise about 2.0 in through impact. This is the baseline for the club, and a range-screen photo on the next swing will turn the estimates into his own numbers.

Strength

Tempo and quiet base

3.0:1 tempo, hips hold their depth (−0.4 in at impact), and the rear of the hips stays on the tush line (0.4 in gap).

Priority 1

Stay tall

The head is ~6.4 in lower than at address at impact. Keeping the cap closer to its address line should help the club meet the ball on a steadier path.

Priority 2

Calm the hip rise

The hips rise about 2.0 in by impact. Holding waist height closer to the dashed waist line should make the low point easier to repeat.

2 Ball & club speed — estimated from the video

Metric	Estimate	Range	Source
Club speed	~81 mph	73–89 mph	Estimated
Ball speed	~117 mph	105–128 mph	Estimated
Carry	~165 yds	145–185 yds	Estimated

Not measured: no range screen in this clip. No range-screen data for the 3-Hybrid yet: scaled from your 11 measured shots with other clubs against a fixed reference table. Confidence: low. 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.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. The backswing starts at frame 100 (~4.82 s), the top is at 5.53 s and impact is at about 5.76 s.

Group	Backswing	Downswing	Ratio
André (3-hybrid, Oct 11)	~0.70 s	~0.23 s	~3.0:1
André (8-iron, 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 the ratio by roughly ±0.2. The top was found from hand tracking, the last frame before the hands reverse direction (checked by eye).

What it means: The ratio matches Tour Tempo. The backswing (0.70 s) is a little shorter than the Tour's 0.80 s and the downswing (0.23 s) a little quicker than 0.27 s. It's a smooth, well-paced swing, and the scorecard rates it Good.

4 The reference frame — how this swing was measured

Grid and scale: each square is about 5 inches (~56 px at 11.26 px per inch). Height wasn't given, so the grid is scaled from his body size in the frame. Treat distances as ±1 inch.
Center lines: the gold vertical line runs through the center of his stance and the horizontal line through the ball line. The gold lines and the bronze diagonals cross at the belt buckle at address, giving a fixed reference for balance and height.
Diagonals and depth rays: the corner-to-corner diagonals give depth perspective, and the mat edges extended to the horizon are the depth rays. Only one stick runs toward the target, so the sticks alone give no reliable vanishing point.
Address references: the white line is the cap (head height). The dashed light-blue lines mark shoulder and knee height. The dashed orange line is waist height. The dashed red tush line is the back of the hips at address in this down-the-line view. The red trail is the head path and the yellow trail the hands' path.
Body and rotation: head height, waist height, and hip and shoulder rotation are compared with address at every key position. Rotation angles are visual estimates (about ±10-15°). X-factor is shoulder turn minus hip turn at the top.
Tracking and camera: body points were tracked automatically on 240 frames (about 1.5-9.5 s), then checked by eye at each key position. The camera stayed still: the background moved less than 0.3 px.

Photos are numbered in the order they happen in the swing. The frames follow the standard swing positions.

6 Position-by-position biomechanics

Photo 1 — Address Good

Tall, relaxed posture: knees flexed, arms hanging, hands just ahead of the ball, which sits at the end of the cross stick.
The cap line and the tush line are set here, so every later position is measured against them.

Photo 2 — Takeaway Head sinks early

One-piece start: hands, arms and club leave together (hands ~10 in from their address spot).
The head is already ~5.4 in lower than at address and ~2.9 in toward the ball line. The hips move ~1.9 in away from the ball, which is a good turn.

Photo 3 — Lead arm parallel Good width

Wide arc with the wrists setting; the hands are ~20 in from their address spot.
The head is ~5.7 in down, and the hips are ~2.1 in away from the ball and ~1.6 in higher.

Photo 4 — Top Good turn

Shoulders turned about 85° and hips about 40°, so the X-factor is about 45° (visual estimate, ±10-15°).
The head is ~4.3 in lower than at address, the best of the backswing. The hips are ~3.0 in away from the ball, so they turn instead of sliding in.

Photo 5 — Arm parallel (down) Good

The lower body leads the downswing and the hands drop inside the line they went up on (yellow trail).
The head is ~4.7 in down, and the hips are still ~2.0 in away from the ball.

Photo 6 — Delivery Solid

The arms are in front of the chest and the club comes from the inside; the hands are ~12 in from their address spot and closing fast.
The hips are ~1.4 in from the ball line and getting closer, which is the natural move into impact. The head is ~5.6 in down.

Photo 7 — Impact Watch the head

The head is ~6.4 in lower than at address (Fix) and ~2.1 in toward the ball (Watch).
The hips stay back (−0.4 in) and the rear of the hips is 0.4 in from the tush line (Good). They rise ~2.0 in (Watch).
The hands are ~2.3 in from their address spot (Watch). The shoulders are about 15° open and the hips about 35° open (visual estimate).

Photo 8 — Release Full extension

Both arms extend toward the target and the chest keeps turning.
The head sits ~7.4 in below its address height at this frame, the lowest point of the swing.

Photo 9 — Finish Excellent

Tall and balanced on the lead leg, trail foot up on its toe, belt buckle to the target.
The head ends ~6.7 in above its address height, so he stands fully up and holds the pose.

Depth note: from behind, the head's shift is partly sideways and partly along the depth rays (toward the target). The mat edges give depth rays, but only one stick converges, so the vanishing point isn't reliable. One camera can't split the two, and a face-on clip of the next swing will settle it. The ball itself couldn't be tracked: at 30 fps it's gone between two frames after impact. A slow-motion clip (120 or 240 fps) would show its start direction.

7 One pattern, the whole bag

Club (best report)	Session	Tempo	Ball speed
3-Hybrid · this report	Oct 11	~3.0:1 (0.70 s / 0.23 s)	no screen data
3-Wood	Oct 24	~1.7:1 (0.50 s / 0.30 s)	121 mph
4-Iron	Oct 7	~1.9:1 (0.50 s / 0.27 s)	110 mph
5-Iron	Oct 2	~1.9:1 (0.53 s / 0.28 s)	108 mph
6-Iron	Oct 14	~2.6:1 (0.60 s / 0.23 s)	107 mph
8-Iron	Nov 4	~5.2:1 (1.90 s / 0.37 s)	94.0 mph

The link: across the bag his tempo swings from 1.7:1 (3-wood) to 5.2:1 (8-iron), and the 3-hybrid lands right on the 3:1 Tour mark, so the timing here is worth remembering for the other long clubs. The body pattern to carry across clubs is the head height: the sinking is already there at the takeaway (~5.4 in) and grows to ~6.4 in at impact, so it's a set-up and early-backswing habit, not just a downswing one. The hips staying back, on the other hand, is a pattern worth keeping.

8 Diagnosis

Tempo is a strength: 3.0:1 (0.70 s / 0.23 s) matches Tour Tempo and the scorecard rates it Good.
The base is quiet: the hips stay back (−0.4 in) and the rear of the hips stays within 0.4 in of the tush line, so there is no early extension.
The head sinks ~6.4 in by impact and ~7.4 in by the release, starting at the takeaway (~5.4 in). It is the main fix. A lower head means the low point of the swing is harder to repeat.
The hips rise ~2.0 in through impact (Watch), and the head is ~2.1 in toward the ball (Watch). Together they show some standing up through the strike.
The coil is healthy: shoulders ~85°, hips ~40°, X-factor ~45°, and the hips open ~35° at impact (visual estimates, ±10-15°).
No measured ball flight: without the range screen, the ball estimates (~117 mph ball speed, ~165 yds carry, low confidence) only come from his other clubs and say nothing about this swing's contact.

Confidence: high on tempo (measured frame by frame, ±0.03 s); moderate on head and hip distances (grid scaled from body size, ±1 inch); low to moderate on rotation angles (visual estimate, ±10-15°); none on ball flight (no range screen; the estimates are low confidence); low on the toward-ball vs toward-target split (needs a second angle).

9 Next steps — keep it simple

Priority 1 · Stay tall

Cap-on-the-line check

Same camera spot. Keep the top of the cap on the white address line until the ball is gone, for 10 balls.

Feel: "chest over the ball, knees keep their flex." This targets the ~6.4 in head drop.

Priority 2 · Hip height

Waist-line check

Film 5 balls and watch the belt buckle against the dashed waist line. The aim is to stay within about 1 in of it through impact.

The hips rose ~2.0 in, and quieter hips make the low point easier to repeat.

Keep · Tempo

Count it the same way

Keep the same smooth count, "back-2-3, down-1", on every hybrid and long-club swing.

It produced a 3.0:1 ratio, the same as Tour Tempo.

Keep · Hips back

Back pockets on the line

Keep the back pockets on the tush line through impact, as they were here (0.4 in gap).

It's what keeps early extension away.

10 Limitations & next capture

One swing is a snapshot. No range screen was captured for it, so no ball data is measured.
The ball estimates come from his other clubs and are low confidence. Ball speed, club speed and spin are not measured.
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, and the sticks give no reliable vanishing point.
Filmed at 30 fps, so the ball could not be tracked after impact.

Next capture: Next capture, to sharpen this report: (1) a photo of the range screen right after each shot, (2) a slow-motion clip (120 or 240 fps) so the ball can be followed, (3) a face-on clip at chest height to split depth from sideways motion, (4) 3-5 balls for an average, and (5) André's height, to lock the grid scale.
