The faults
The faults that cost you most
Fault 01
Over-the-top slice
Ball starts left and curves hard right. Usually sequencing, not grip.
Fault 02
Early extension
Hips push toward the ball in the downswing — blocks and thin contact.
Fault 03
Casting
Wrist angle released early — speed spent before the ball.

Golf Metrics SwingVantage Analyzes
Every metric is compared to tour-calibrated benchmarks for your club and skill level.
Ball Speed
Measures energy transfer from club to ball. Target smash factor 1.45–1.50.
Club Speed
Raw clubhead velocity. Foundation for distance calculation.
Launch Angle
Vertical angle off the face. Optimal 10–14° for driver.
Spin Rate
Backspin and sidespin govern curve and descent. High spin = ballooning shots.
Club Path
In-to-out vs. out-to-in path is the #1 factor in shot shape.
Face Angle
Where the face points at impact. Determines starting direction.
Face-to-Path
The gap between face and path creates draw or fade. ±2° is considered neutral.
Attack Angle
Negative (hitting down) adds spin and reduces distance on driver.
Dynamic Loft
Actual loft at impact — affected by shaft lean and attack angle.
Smash Factor
Ball speed ÷ club speed. Measures strike quality and sweet spot consistency.
Proof, not just claims
Here's a worked Golfexample on sample data — the same shape your real report takes. We show the evidence, the confidence, and what we honestly can't know.
Example diagnosis
Out-to-in club path with a face open to that path — a classic slice pattern.
Top fix: Shallow the downswing so the club approaches from the inside. Fix the path first; the face is far easier to square once the path is neutral.
What SwingVantage uses
- In the down-the-line view, the club drops outside the target line in transitionEstimated
- Reported ball flight (starts left, curves right) matches an out-to-in path with an open faceInferred
- Upper body appears to start the downswing before the lower body (over-the-top)Inferred
What it can't know
- Exact club path and face angles in degrees (needs a launch monitor)
- Whether equipment (shaft, lie, loft) is contributing
- Anything about wrist or shoulder health — stop if you feel pain
How you'll measure progress
On day 7, re-film one driver swing from the same down-the-line angle and distance. Compare transition (does the club drop inside now?) and start line. Re-record every 1–2 weeks to track the trend, not a single swing.
Coach summary
Player presents an out-to-in path with an open face on the driver. Priority: shallow the transition before any face/grip work. Drills assigned: gate, pump-and-drop, split-hand release. Retest in 7 days from a fixed camera angle.
What do the confidence labels mean?
Illustrative example
Sample data, not your swing — used on demos and the sample reports so you can see the format before you start.
Heuristic estimate
A smart, data-backed read from limited input (a self-report or a single video). It is honest about being an estimate, and it sharpens every time you add a swing.
Measured
Values actually computed from your swing video or imported launch/sensor data are labelled as measured — not estimated.
We always show you which one you are looking at, and never present an estimate as a measurement.
Your swing, decoded — coaching in your pocket. SwingVantage reads your data and hands you the one fix that matters most, with confident, data-backed guidance you can use today. Findings are heuristic estimates — smart reads that sharpen with every swing you add — and they pair perfectly with a coach for injury concerns or advanced technique work, so you show up to those sessions already ahead.
