Gaian · Swing Analysis — Marcelo Klujsza

1 Executive summary

Bottom line: Marcelo has an athletic, well-sequenced driver swing. The head stays centered through the backswing and he holds the wrist angle deep into the downswing. The hips lead the arms, and he finishes in full balance on his lead side. The tempo is about 2.6:1, close to the ~3:1 that skilled players show. These are hard things to learn, and he already does them.

The biggest gains are in the setup for the driver. His stance is about shoulder-width, his shoulders look fairly level, and the shaft leans slightly toward the target at address. That's closer to an iron setup. The driver rewards a wider base and a spine tilted away from the target, which set up an upward strike: higher launch, less spin, more carry. The second priority is measuring the ball. No launch data was available, so distance, speed and spin are benchmarked below but not yet scored.

Strength

Pivot, lag & finish

The head is centered, the wrist angle holds until the hands reach hip height, the extension is full, and he holds a balanced finish facing the target.

Priority 1

Driver-specific setup

A wider stance, spine tilt away from the target and a neutral shaft. Together they set up an upward angle of attack.

Priority 2

3 Swing sequence

Eight key positions from the video, filmed face-on at the Olympic Golf Course.

P-numbers follow the standard 10-position swing model. The video runs at 30 fps, so timestamps are accurate to about ±0.03 s. The impact frame is a split second after contact: the ball is already gone and the tee is still in the ground.

4 Position-by-position biomechanics

P1 — Address Adjust for driver

The ball position is correct, just inside the lead heel, and the posture is relaxed and athletic.
The stance is about shoulder-width. For the driver, a base slightly wider than the shoulders gives more stability for a longer, faster swing.
The shoulders look fairly level, and the shaft leans slightly toward the target. That's an iron setup, which tends to deliver the club level or descending.
Target picture: the trail shoulder lower than the lead, the spine tilted slightly away from the target, the shaft neutral or the grip end pointing at the belt buckle, and the ball teed so half of it sits above the crown of the driver.

P2 — Takeaway Good

A one-piece start: arms, hands and club move away together, with good width.
The head stays centered, with no sway away from the target.

P3 — Halfway back Good

The wrists hinge on time, setting the club up at about lead-arm-parallel.
The lower body stays quiet, while the upper body keeps turning.

P4 — Top of backswing Full & centered

The shaft reaches about parallel to the ground, a full driver backswing without overswinging.
The head stays over the ball rather than drifting away from the target or toward it, so there's no reverse pivot. That makes centered contact repeatable.
Watch: the lead knee moves noticeably toward the trail knee. It's fine as long as the trail knee keeps its flex and doesn't straighten.

P5 — Transition & delivery Strong

The lower body starts the downswing: the lead hip moves toward the target while the club is still above the hands.
Lag: the shaft is still nearly vertical with the hands at chest height. The wrist angle is kept late, which is where clubhead speed comes from.
Tempo: the backswing takes about 0.75 s and the downswing about 0.28–0.30 s, a ratio near 2.6:1. Skilled players sit around 3:1, so he's close.

P7 — Impact Good

The hips are open to the target, the lead leg is posting up, and the trail heel is releasing, a powerful lower-body position.
The head stays at roughly its address position, behind where the ball was.
The driver-specific gain: with a tilted setup, this same motion catches the ball slightly on the upswing. That upward angle of attack is what lets a driver launch higher with less spin.

P8 — Extension Excellent

Both arms extend fully toward the target after impact. That's a sign of a free release, with no chicken wing.
The weight is clearly on the lead side.

P10 — Finish Excellent

A high, full finish: the belt buckle and chest face the target, the trail foot is up on its toe, and the weight is on the lead foot.
He holds his balance, which shows the speed is under control. This is an asset, so keep it.

5 Diagnosis — where the next yards are

Iron-style setup: a shoulder-width stance, fairly level shoulders and the shaft leaning slightly forward.
Level or descending delivery: that setup tends to present the driver at a level or slightly downward angle of attack. That's common among amateurs, and it costs carry.
Higher spin, lower launch: hitting down on a driver adds backspin and lowers launch, so the ball balloons or falls out of the air early. That hurts more in the Olympic Course's coastal wind.
Opportunity: his motion is already efficient, with good lag, sequencing and balance. A setup change could add carry without swinging harder.

Confidence: high on the strengths, which are clearly visible in the frames. Steps 2–3 are moderate, because they're inferred from the setup. Angle of attack, launch and spin can only be confirmed on a launch monitor.

6 Fixes & drills (in priority order)

Priority 1 · Setup

Driver setup checklist

Widen the feet to just outside the shoulders. Tee the ball so half of it sits above the crown. Put the ball inside the lead heel, which he already does. Lower the trail shoulder until the spine tilts slightly away from the target. Grip end at the belt buckle.

Sets up an upward strike before the swing even starts.

Priority 1 · Setup

Trail-hand-on-thigh tilt

At address, slide the trail hand down the outside of the trail thigh, then place it on the grip. Feel the trail side lower and the head slightly behind the ball.

A repeatable way to build in the spine tilt without thinking about it.

Priority 1 · Strike

Tee-in-front drill

Push a second tee into the ground about 4 inches in front of the ball, on the target line. Strike the ball without hitting the front tee.

Rewards an upward, sweeping strike and penalizes a descending blow.

Priority 2 · Data

Baseline launch-monitor session

Hit 10 drivers on a launch monitor (TrackMan, GCQuad or similar) and record club speed, ball speed, smash factor, launch, spin, attack angle and carry.

Puts Marcelo on the benchmark tables and measures every change from here on.

Priority 3 · Tempo

3:1 tempo with a metronome

Rehearse "back-2-3 / down-1" with a tempo app. Start with three-quarter swings, then build to full.

Fine-tuning only: his tempo is already close.

Keep

Hold-the-finish rule

Hold every practice drive in the finish for a three-count.

Protects the balance and full rotation he already has.

7 4-week practice plan

Week	Focus	Session (≈50 balls)
1	Baseline & setup	Launch-monitor baseline (10 drivers) · set up the checklist in a mirror (5 min) · 30 drivers with the new setup at 80% effort
2	Upward strike	20 tee-in-front shots · 20 full drivers · 10 shots logging attack angle and launch
3	Speed & tempo	Metronome rehearsals · 20 drivers at 3:1 tempo · 20 full-speed drivers holding the finish
4	On-course test	9 holes at the Olympic Course: log fairways hit and estimated carry into the wind and downwind · 10-shot retest on the monitor against week 1

Targets to track on the monitor

Attack angle: level or negative → 0° to +4° (upward)

Launch angle: → 12–15°

Spin rate: → 2,200–2,800 rpm (lower end in wind)

Smash factor: → 1.45+ (center contact)

The target ranges are general driver optimization windows for amateur club speeds. Refine them once the baseline session gives his actual club speed.

8 Limitations & next capture

The analysis covers one swing, filmed face-on only. Swing plane, club path and posture at the top need a down-the-line view.
There's no launch data and no ball flight in the frame, so speed, distance, spin and shot shape weren't measured.
At 30 fps the club blurs through impact, so the exact impact frame and shaft lean at contact are approximate.

For the next session: film face-on and down-the-line with the camera at hand height, using slow motion (120–240 fps). Hit 10 drivers on a launch monitor and capture the averages.
