André Rennes

A frame-by-frame review of André's 6-iron swing at Crystal Springs, filmed from behind. It covers set-up, tempo, head motion, impact and finish, compares it with his first 6-iron report, and closes with simple next steps.

1 Executive summary

Bottom line: a solid, repeatable 6-iron motion with one clear improvement. The hips held their depth through impact: no early extension, which the 7-iron still showed. The finish was full and balanced again, and the tempo measured ~2:1 (0.53 s back, 0.27 s down), identical to his first 6-iron.

The pattern still to fix is the same as in every club so far: the head sinks about 5 inches by impact (3 of them already by the top). There was no range screen, so ball flight is estimated: ~145–150 yds total on flat ground (~155 yds seen on the downhill range), with launch still high at ~22–23°.

Strength

Hips stay back

Seat on its address line at impact, plus a full, balanced finish.

Priority 1

Stay tall

Keep the cap at its address height to the top and through impact.

Priority 2

Slower back

Stretch the backswing toward the 2.8:1 of his best wedge.

2 Ball flight — estimated from the video

No range screen on this clip, so these numbers are estimates (±10 yds), not measurements.

Ball speed~102–106 mph109 mph127 mph
Launch angle~22–23°17.1°~14°

Total (flat)~145–150 yds——
Seen on the range~155 yds——

Method: André's height (1.80 m) sets the scale, about 0.24 cm per pixel. The clubhead covers ~74 cm in the frame before impact, ~50 mph in the picture plane. That's a floor, since from behind most of the motion runs into the picture. The range is filled in from his own data: tempo, head dip and posture match his 6-iron #1 (75–77 mph) and 7-iron (76–78 mph). Benchmarks: TrackMan PGA Tour and LPGA Tour averages (6-iron).

What it means: the Crystal Springs range runs downhill, worth about 25 yds here. The ~155 yds André saw is therefore ~130 yds on flat ground, about 15 yds under the estimate, which points to a slightly thin or high-launched strike. Either way his speed is LPGA-level, but the distance isn't yet. The cause is the same as in his other irons: the head dip adds loft (~22° vs 17°). Fixing it is worth roughly 10–15 yds.

3 Timing & tempo — measured from the video

30 frames per second, so each time is accurate to about ±0.03 s. Takeaway starts at 46.40 s, the top is at 46.94 s, and impact is at 47.20 s.

GroupBackswingDownswingRatio
André (6-iron #2, today)~0.53 s~0.27 s~2:1
André (6-iron #1, Oct 6)~0.45–0.6 s~0.23–0.3 s~2:1
André (PW #2, Oct 11)~0.60 s~0.22 s~2.8:1
PGA Tour (Tour Tempo, "24/8")~0.80 s~0.27 s3:1

Tour figure: John Novosel, Tour Tempo. One frame either way moves the ratio between ~1.8:1 and ~2.2:1.

What it means: the downswing (0.27 s) is already tour-speed. The gap to 3:1 is all in the backswing, which is about a quarter-second quicker than tour players'. Same story as the 7-iron.

5 Position-by-position biomechanics

Photo 1 — Address Good

  • Athletic posture: knees flexed, back straight, arms hanging under the shoulders.
  • Red alignment stick on the mat just past the ball, a clear visual for the line.
  • A long wait over the ball (about 28 s at address before the takeaway). A 10–15 s routine keeps the hands and shoulders free of tension.

Photo 2 — Takeaway Good

  • One-piece start: arms, hands and club move away together.
  • Smooth, unhurried first move.

Photo 3 — Lead arm parallel Good width

  • Wide arc, wrists setting on time.
  • Trail knee keeps its flex: a stable base.

Photo 4 — Top High hands

  • Full shoulder turn, hands finishing above the head (his usual high-hands top).
  • The head is already about 3 inches lower than at address.
  • Shaft short of parallel, a good length for control.

Photo 5 — Lead arm parallel (down) Good

  • Wrist angle holds as the arms drop.
  • Lower body leads the downswing.

Photo 6 — Delivery Solid

  • Hands drop in front of the trail thigh, arms stay connected to the chest.
  • No sign of an over-the-top move from this angle.

Photo 7 — Impact Watch the head

  • The head is about 5 inches lower than at address and ~2 inches closer to the ball.
  • New positive: the hips keep their depth. The seat stays on its address line, so no early extension this time (the 7-iron showed ~2 in).
  • Hands roughly level with the ball. Shaft lean can't be judged precisely from behind.

Photo 8 — Release Full extension

  • Both arms extend through, chest keeps turning.

Photo 9 — Finish Excellent

  • Tall and balanced on the lead leg, trail foot up on its toe, belt buckle to the target.
  • Held to the end of the clip, as in every report.

Overlay — head at address, top and impact

The white line is the top of the cap at address, and the gold line is the back of the cap at address. The camera didn't move. Distances are estimated from his body size in the frame (shin length), so treat them as ±1 inch.

Still open: the Oct 14 7-iron carried 4 yards farther than the Oct 6 6-iron (gap only 2 yds total). A 6-iron with range-screen data is still needed to settle the gap. That's the top item for the next 6-iron session.

7 Diagnosis

  1. Lower body is improving: hips keep their depth through impact and the finish is complete.
  2. The head sinks about 5 inches, 3 of them in the backswing. It's the same pattern seen in his driver, 4-, 5-, 6- and 7-iron and wedge videos, and the main reason his irons launch high.
  3. Tempo is a steady ~2:1. A slower backswing is the one change that moves it toward 3:1.

Confidence: high on tempo (measured); moderate on head distances; low-to-moderate on ball flight (estimated) (estimated from body size); hip depth reliable from this angle.

8 Next steps — keep it simple

Priority 1 · Stay tall

Cap-on-the-line check

Same camera spot. Mark the top of the cap at address on the screen and hit 10 balls trying to keep it on that line until the ball is gone, starting with the backswing.

Feel: "chest stays over the ball, knees keep their flex."

Priority 2 · Tempo

Wedge rhythm, longer club

Count "back-2-3, down-1", the same count as the 2.8:1 wedge swing.

Slows the backswing without touching the downswing speed.

Routine

10-second set-up

Once the club is grounded, go within 10–15 s. Today's address lasted about 28 s.

Less time over the ball means less tension in the hands.

Keep

Hips back, full finish

Same seat depth through impact and the same held finish on every swing.

It's the clearest improvement in this report.

9 Limitations & next capture

Next session: a 6-iron with the range screen in shot (5 balls for an average) to settle the 6/7 gap, plus one face-on clip at chest height.
