What the coach measures
One clip, one angle — here's what each angle can read. Film the other angle another day for the rest.
Backswing time divided by downswing time. Tour players measured with electronics in the club shaft run 2.5 to 3.5, averaging near 3:1 - three counts back, one count down. We time your hands rather than your club, which reads a little lower than a shaft sensor does, so a number in the low 2s is not by itself proof you rushed it.
How long your backswing takes, from the takeaway to the top. Every golfer ever measured with sensors in the club - tour professionals through 25-handicappers - takes between 0.69 and 0.83 seconds, and this window sits around that. It is a coarse read: we time your hands, not the club, so it can tell a snatch from a dawdle but not a tour swing from a good amateur one.
How much your head slides sideways going back. A steady head keeps you centered over the ball. In the one study that split golfers by skill, the low-handicap group averaged about 0.14 torso-lengths of head slide at the top and the 17-handicap group about 0.31 - eight golfers in total, so read the edges as indicative.
How straight your lead arm stays at the top. A firm (not locked) lead arm keeps your swing arc wide.
How much your hips slide sideways instead of turning. A little is natural - a lot means you're swaying, not coiling.
Feet width compared to your shoulders. Around shoulder-width gives you a stable base to turn against.

Athletic knee bend at address. Eleven Korea PGA professionals average about 156 degrees here (24 degrees of bend), and this window is that average give or take. Standing too tall or crouching too much both make a consistent strike harder.
How settled you are before the takeaway. A quiet setup makes a repeatable first move. Scored as 1 minus setup motion over the stillness threshold (vStill 0.35 TL/s); pose-tracking jitter alone reads about 0.14 TL/s on a motionless golfer, so a rock-still setup tops out near 0.6 rather than 1.0 - that is why ideal starts at 0.5 and a fidgety setup falls away below 0.3. Bands calibrated at that noise floor on thin data (one measured real swing), so treat mid-band readings gently.
How much your head drops or rises by impact. Big changes make clean contact a coin flip.
A full, held finish - hands high, weight on the front foot, balanced - means you committed to the shot.
A category the clip can't show clearly comes back blank rather than guessed — and if too much of the movement is unreadable, we hold the overall score back instead of averaging what is left.
The report, start to finish
Explore it — this is the layout you get. The numbers below are a worked example, not a recording of someone's clip.
Drills the coach prescribes
Stand with your feet touching and hit half-shots at 50% effort. You physically can't lunge or sway - the drill forces rhythm and centered contact.
Swing to the top, say 'one' out loud while you pause a full beat, then swing through. Kills the snatch from the top.
Count 'one-two-three' during the backswing and 'one' for the downswing - that matches the 3:1 tour tempo.
Swing your lead arm to 9 o'clock with wrists hinged into an 'L', then swing through to a mirrored 'L' on the other side. Builds arm structure and release.
How to film it
- ✓ Film portrait from waist height, 8-10 feet away - you should stand about half the frame tall, head to feet. Below about two fifths of the frame the clip can be rejected, and golf has no auto-zoom to rescue it
- ✓ Whole body and club in the frame, including the top of the backswing
- ✓ Phone steady - lean it on your bag or a bottle. Stillness at address, sway and head steadiness in the backswing, and the impact reads (hips into impact, head level, head behind the ball) are all thrown away if the camera moves
- ✓ One swing per clip; settle over the ball for a second before you start it, and let the clip run past your finish
- ✓ Sun behind the phone, not behind you
- ✓ Normal playback speed, not slo-mo - we time the swing from how fast your hands move through the ball, and a slowed-down clip can come back refused for having nothing fast in it. 60 fps is fine as long as it isn't your camera's slo-mo mode
