Confidence Score

Also known as: diagnostic confidence

Definition

A confidence score is a 0–100 calibration of how much to trust a finding, scaled by sample size, shot-to-shot consistency, and how complete your inputs were.

The confidence score is SwingVantage's way of telling you how much evidence supports each finding in your report. It is expressed as a number from 0 to 100, where higher numbers indicate stronger, more consistent evidence across your submitted data. A score of 80 or above means the pattern appeared clearly and repeatedly — the finding is reliable and you can act on it with confidence. A score below 50 means the finding is plausible but the data was thin or uneven. It is worth noting but warrants more evidence before committing to a significant technique change.

The score is calculated from three components. Sample size affects the score directly: a finding based on ten consistent shots scores higher than the same finding from a single shot. Shot-to-shot consistency matters: if the fault pattern is present in every shot, the score rises; if it is intermittent, the score reflects that uncertainty. Input completeness also contributes. This means a session with video, ball flight data, and self-reported symptoms scores higher than a session with video only. This is. This is because more inputs can corroborate or contradict the initial finding.

Confidence scores are intentionally visible rather than hidden in the system. SwingVantage does not suppress low-confidence findings and present only high-confidence ones. This means that would hide the uncertainty and give the appearance of greater certainty than the data supports. Instead, all findings are shown with their confidence score so you can make an informed judgment about how much weight to give each one. The goal is to be useful without overclaiming. This means a finding labeled 45/100 is still actionable as a hypothesis to investigate, as long as it is not treated as a proven fact.

Beginner tip

Do not ignore findings with lower confidence scores, but do not restructure your technique around them either. A score of 50–65 is a signal worth watching. This means upload another session or two and see whether the confidence rises or the finding drops out. If it rises, it is real; if it disappears, it was noise.

Advanced note

If you want to actively raise a confidence score, the most efficient approach is to upload multiple sessions filmed from a consistent angle under consistent conditions. Variability in camera angle, lighting, or session conditions introduces ambiguity that lowers the score even when the underlying pattern is real and consistent.

Example

One blurry video yields a 45/100 confidence read; three consistent clips of the same swing raise it to 80.

Why it matters

Honest confidence is what separates a trustworthy tool from a confident-sounding guess. You always see how sure the system is.

How it shows up on video

The confidence score is displayed numerically alongside every finding in the report — look for the "(Confidence: XX/100)" notation. High confidence (above 70) typically correlates with clean video, 10+ swings in the session. The fault appearing reliably across clips. Low confidence (below 50) signals limited or noisy data.

Common mistakes

Treating a low-confidence finding as equally actionable as a high-confidence finding. This means low confidence means limited evidence, not absence of a fault. Verify with a larger, better-quality session before committing to a drill change.
Ignoring confidence scores entirely and focusing only on the finding label. This means the score is the critical context that tells you how much certainty to attach to the label.
Not improving confidence by recording more or better-quality sessions. This means confidence increases as you add data. If a finding feels wrong, add sessions to either raise the confidence or shift the finding.
Confusing confidence score with importance. This means a finding with 45% confidence can describe a genuinely important fault. Confidence reflects the evidence level, not the severity of the problem.

In SwingVantage Motion Lab

Confidence scores appear on every finding card in your SwingVantage report. They update on its own as you add more sessions. This means the same fault identified at 55/100 in your first session may reach 80/100 after three consistent sessions showing the same pattern. The score also determines how advice are phrased: high-confidence findings receive direct, actionable language; low-confidence findings are phrased as hypotheses to explore.

Frequently asked questions

Is a confidence score of 100 achievable?

In practice, very high scores (90+) are achievable with large, consistent datasets, but the system is designed to never claim certainty it cannot support. A score of 85–90 from multiple consistent sessions with measured data is a high-confidence, reliable finding. The exact ceiling varies by fault type. This means some patterns are inherently harder to detect with certainty from video alone. This caps their achievable confidence below what a sensor-measured equivalent could reach.

Why does my confidence score drop after I add a new session?

A confidence score can drop temporarily when a new session shows a different pattern than the existing baseline. This is correct behavior. This means if your most recent session shows the fault clearly but previous sessions do not, the score reflects the uneven results in the dataset, not just the most recent result. Continued sessions will either confirm the pattern (raising the score) or suggest the fault is intermittent (which is itself a useful diagnosis).
