How is a fault different from a symptom?

A symptom is what you see (a slice, a fat shot); a fault is the underlying cause. One root fault often creates several symptoms, which is why fixing the cause beats chasing each miss.

How does SwingVantage detect a swing fault?

It reads setup, path, sequencing, balance, and ball-flight consequences from your video and inputs, then maps them to the most likely fault — labeling how confident the read is.

Why does SwingVantage show only one main fault?

Because fixing the single highest-impact root fault usually clears several symptoms at once. Leading with one fix keeps practice focused instead of overwhelming you with a long list.

Are swing faults the same in every sport?

The principle is the same, but the specific faults differ by sport. SwingVantage uses each sport’s mechanics so a baseball bat-path fault and a golf plane fault are each judged on their own terms.

What Is a Swing Fault?

A swing fault is a specific, repeatable flaw in your motion — like an over-the-top path or early extension — that drives your misses. SwingVantage detects faults from video and inputs, then prioritizes the one root fault most responsible for your results, because a single fault often produces several visible symptoms.

Cause vs. symptom

A fault is the cause, not the miss

A slice, a fat shot, a pop-up — those are symptoms. A swing fault is the underlying cause: a specific, repeatable flaw like an over-the-top path or early extension. One root fault often creates several symptoms, which is why chasing each miss rarely works.

Symptom

What you see in the result — the ball flight or contact.

Fault

The named movement error that produced it.

Root fault

The single fault driving the most symptoms — your top fix.

How we find it

Detecting and ranking faults

SwingVantage reads setup, path, sequencing, balance, and ball-flight consequences from your video and inputs, maps them to the most likely fault with a structured and AI read, and labels how confident it is. Then it prioritizes the one root fault most responsible for your results — see the canonical explainers in the data points library.

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.

Frequently asked questions

What is a swing fault?: A swing fault is a specific, repeatable flaw in your technique — such as coming over the top or early extension — that causes poor contact or unwanted ball flight. It is a named cause, not just a bad result.
