1 Executive summary

Bottom line: this is a free-flowing, athletic driver motion with tour-like rhythm. On both swings the backswing takes about 0.75 s and the downswing about 0.22 s, a ratio of about 3.3:1. That's close to the 3:1 measured across tour players and better than most amateurs. The head loads slightly behind the ball and returns to its address spot at impact, and he finishes in balance.

Three things limit consistency and speed. The backswing goes past parallel with the trail elbow lifting away from the body. The trail leg straightens and the lead knee collapses inward at the top, which bleeds ground force. And the tee sits too far back in the stance for a driver, about 3–4 inches inside the lead heel.

Strength

Rhythm & centre

~3.3:1 tempo on both swings, a stable head that returns to address at impact, and a full, balanced finish.

Priority 1

Length & structure at the top

Shorten the backswing to parallel and keep the trail elbow pointing down, so the club returns on the same path every time.

Priority 2

Legs & ball position

Hold trail-knee flex, keep the lead knee over the toes, and move the tee forward to the lead heel.

2 Timing & tempo — measured from the video

The video runs at 30 frames per second, so each time is accurate to about ±0.03 s. Swing 2 is the main reference; swing 1 confirms it.

Measure	Swing 1	Swing 2	Reading
Backswing (takeaway → top)	0.77 s	0.77 s	Repeatable
Downswing (top → impact)	0.20 s	0.23 s	Fast, aggressive
Total swing time	0.97 s	1.00 s	Tour-like total
Tempo ratio	~3.8:1	~3.3:1	Near the 3:1 target

How the timing compares

Group	Backswing	Downswing	Ratio
Golfer	~0.77 s	~0.22 s	~3.3:1
PGA Tour (Tour Tempo, "24/8")	~0.80 s	~0.27 s	3:1
LPGA Tour	~0.80–0.90 s	~0.27–0.30 s	≈3:1
Low-handicap amateurs (0–5)	~0.80–0.95 s	~0.27–0.32 s	≈3:1
Average amateurs	often 1.0 s+	~0.30–0.40 s	varies widely

The tour figures come from John Novosel's frame counts in Tour Tempo. The amateur and LPGA ranges are typical values from the same research and coaching literature, not one official table.

What it means: rhythm is not his problem. He already owns the ratio most amateurs never find. The very quick downswing (~0.20–0.23 s) shows real speed potential. The work is in what happens at the top, not in the timing.

3 Swing sequence

Nine key positions from swing 2, filmed face-on. The golfer is right-handed, so the target is to the right of the image.

P-numbers follow the standard 10-position swing model. Impact is the frame where the clubhead blurs through the tee.

4 Position-by-position biomechanics

P1 — Address Ball position

A wide stance, wider than the shoulders, gives a stable base for a driver. That's good.
The tee sits a little forward of centre, about 3–4 inches inside the lead heel. For a driver it belongs opposite the lead heel, so the club catches the ball on the way up.
The upper body is fairly centred over the belt buckle. A driver set-up wants the trail shoulder a little lower, with the spine tilted 5–10° away from the target.

P2 — Shaft parallel Good

A wide, one-piece takeaway: arms, hands and club move away together, and the lead arm stays straight.
The head stays still, and the lower body is quiet.

P3 — Lead arm parallel Good width

The wrists have set and the lead arm is long and straight, which creates a big arc.
The upper body shifts about 3 inches toward the trail side. That's a healthy, controlled load for a driver.

P4 — Top of backswing Key issue

Past parallel: the club travels about 15–20° beyond horizontal, on both swings.
Trail elbow lifts up and away from the body ("flying elbow"). The hands finish high over the head.
Legs: the trail leg almost straightens, and the lead knee collapses in toward the ball. The hips over-turn and the structure that stores power is lost.
Together these make the top long and loose, so the downswing has to re-route the club. That works on a good day but varies from swing to swing.

P5 — Lead arm parallel (down) Good lag

The hips start the downswing, and the wrists keep a sharp angle between the lead arm and the shaft. That's stored lag, a speed source.
The lead knee moves back out over the lead foot as the weight shifts.

P6 — Shaft parallel (down) Solid

The hands are at the trail thigh with the shaft parallel to the ground, a sound delivery position.
The body weight is moving into the lead side, and the head stays behind the hands.

P7 — Impact Centred

The head is back on its address spot: the overlay line lands on the cap again (see below).
The hips have opened toward the target and the lead leg is posting up. That's where speed comes from.
The trail heel is already lifting, which is normal for a driver at this speed.

P8 — Release Full extension

Both arms extend toward the target after impact, with no chicken wing.
The trail knee drives toward the lead knee, showing full weight transfer.

P10 — Finish Excellent

Tall and balanced on the lead leg, with the belt facing the target and the trail foot up on its toe.
He holds it, which shows he controls the speed he creates.

Overlay — head position at address, top and impact

The white line marks the centre of the head at address. At the top the head has moved about 3 inches to the trail side, a normal load. At impact it's back on the line. The camera was handheld, so treat the numbers as ±1 inch.

5 Driver benchmarks — where these positions lead

No ball was hit, so club speed and ball data can't be measured from this video. The table shows published driver averages so the next session with a ball can be placed straight away.

Metric	Average male amateur	Low-handicap amateur	LPGA Tour	PGA Tour
Club speed	~93 mph	~105–110 mph	96 mph	115 mph
Ball speed	~133 mph	~155–160 mph	140 mph	171 mph
Launch angle	~13°	~12–13°	13.2°	10.4°
Spin rate	~3,000 rpm	~2,700 rpm	2,611 rpm	2,545 rpm
Carry	~214 yds	~250–260 yds	218 yds	282 yds
Tempo ratio	varies	≈3:1	≈3:1	3:1

Tour figures: TrackMan 2024 tour averages. Amateur figures: TrackMan amateur averages by handicap (rounded); "low-handicap" means roughly 0–5.

Where he likely sits: his downswing time and lag point to above-average speed, plausibly in the low-handicap range. The past-parallel top and leg action are the usual reasons that speed doesn't turn into consistent centre contact. A launch monitor session will confirm it.

6 Diagnosis

The engine is good: tour-like tempo, real lag, a stable head and a full release. These are hard to teach, and he already has them.
The top is too long and loose: the club goes past parallel, the trail elbow flies, and the hands get very high. The downswing then has to re-route the club, which costs consistency.
The legs give away their structure: the trail leg straightens and the lead knee caves in. The hips over-turn and lose the ground pressure that powers the downswing.
The set-up limits the strike: the tee 3–4 inches back with a centred spine favours a level or descending blow. A driver wants an upward strike off the lead heel.

Confidence: high on the timing, the head motion and the length at the top, which are measured. Moderate on the trail-elbow and knee detail, which a down-the-line view would confirm.

7 Fixes & drills (in priority order)

Priority 1 · Length

Three-quarter "stop at parallel" swings

Make swings where the club stops at parallel over the trail shoulder, with a mirror or phone check. Then hit balls with that feel.

A shorter top keeps the arms connected and the club on plane, and usually adds speed rather than costing it.

Priority 1 · Trail elbow

Towel under the trail arm

Tuck a small towel under the trail armpit and make half to three-quarter swings without dropping it.

Keeps the trail elbow pointing down at the top, which ends the flying elbow.

Priority 1 · Legs

Ball under the trail foot

Put a golf ball under the outside edge of the trail foot and make backswings, keeping the trail knee flexed and the lead knee pointing at the lead foot.

Builds pressure on the inside of the trail leg and stops the trail leg straightening.

Priority 2 · Set-up

Driver set-up checklist

Tee opposite the lead heel; trail shoulder lower than the lead; head behind the ball; weight about 55% on the trail side.

Builds an upward strike: higher launch, less spin, more carry.

Keep

Tempo check

Once a week, rehearse with a 24/8 Tour Tempo track to keep the ratio he already has.

Protects his natural rhythm while the top changes.

Keep

Hold-the-finish rule

Hold every swing in the finish for a three-count.

Locks in balance as the new top position settles.

9 Limitations & next capture

No ball was hit, so club speed, ball speed, launch, spin, carry and direction can't be measured. The benchmarks are reference values only.
The footage is face-on only. The swing plane, the trail elbow and spine angle are best judged down-the-line.
The camera was handheld, at 30 fps. Positions are accurate to about ±1 inch and times to ±0.03 s.

For the next session: hit 5–10 drivers on a launch monitor. Film face-on and down-the-line from 3–4 m away, on a tripod at hand height, in slow motion (120–240 fps) if possible.
