Evidence Label
An evidence label separates what SwingVantage measured (a sensor or launch-monitor number) from what it estimated (an inferred likely pattern). As a result, an estimate is never presented as a lab measurement.
Every value in a SwingVantage report carries a provenance tag — an evidence label — that tells you how that value was obtained. The two primary categories are "measured" (the value came directly from a sensor, launch monitor, or tracking device you connected or imported) and "estimated" or "heuristic" (the value was inferred from observable cues using the rules library). This labeling is not optional or stylistic; it is a core honesty commitment built into the platform from the ground up. You will never see an estimated value presented without its label, and measured values are likewise tagged to their source. As a result, you know which instrument produced them.
The motivation for evidence labels is the difference between trust and false precision. If every value in a report looked equally authoritative regardless of how it was obtained, you could not distinguish a direct Trackman reading from an inference from a phone video. That ambiguity would undermine the entire diagnostic process. This means you would not know how much confidence to place in each number. The analysis would feel either more or less reliable than it actually is. By making provenance explicit, SwingVantage lets you interpret each value appropriately. This means act decisively on measured data, treat estimated data as a well-informed starting point, and seek additional measurement when the stakes of a decision require it.
Evidence labels also serve a progress function. As you add measured data to sessions that previously contained only estimates, the labels update. An "estimated" spin rate that becomes "measured" after a launch monitor import is a visible record of the growing precision of your data. This means you can see your knowledge of your own swing improving over time, not just your technique.
When reading your report, check the evidence label on the values driving the primary advice. If those values are labeled "estimated," consider whether a measured session would meaningfully change the diagnosis before acting on a significant technique change.
Use evidence labels strategically when planning data collection. If a specific metric is driving a high-severity finding but is currently "estimated," prioritize getting a measured session for that metric. This means a single relevant measurement can sharply raise confidence in the finding and eliminate ambiguity about whether the fault is real.
Example
A report shows exit velocity as "measured" from imported data but launch angle as "estimated" from video — clearly tagged.
Why it matters
Knowing measured-vs-estimated is the difference between trust and false precision. SwingVantage never blurs that line.
How it shows up on video
Evidence labels are visible on every metric and finding in the report and Motion Lab. This means look for the badge in brackets. This means [Measured], [Estimated], [AI Interpreted], [Placeholder]. Checking the evidence label before reading a value takes one second and tells you how much certainty to apply.
Common mistakes
- Not looking at evidence labels before forming an opinion about a finding — the label is the first piece of context you need, not an afterthought.
- Sharing analysis results with a coach without including the evidence labels. This means a coach reading "path. This means +7 degrees" needs to know whether that is measured or estimated to advise correctly.
- Assuming the same finding label across two sessions means they have equal evidence quality. This means the evidence label type may be the same (both "Estimated"). At the same time, the underlying confidence scores differ by a lot.
- Treating an "AI Interpreted" label as less reliable than an "Estimated" label in all cases. This means AI interpretations can be more informative than simple estimates for complex multi-signal patterns, provided the underlying data quality is high.
In SwingVantage Motion Lab
Evidence labels appear on every metric value card in your SwingVantage report. When you import data from a connected launch monitor or device, the labels for those metrics update from "estimated" to "measured" on its own. The label is always visible alongside the value — it is never buried in a tooltip or hidden in a settings panel.
Frequently asked questions
What does "inferred" mean as an evidence label?
"Inferred" (also labeled "heuristic" or "estimated" in different parts of the interface) means the value was derived from observable indirect cues rather than measured directly. For example, a likely swing direction inferred from ball flight and video is an inferred value. It is the engine's best estimate based on available evidence, clearly distinguished from a directly measured number.
Are there evidence labels besides "measured" and "estimated"?
Yes. This means some values are labeled "imported" (the value came from a third-party data file you uploaded, such as a CSV export from a launch monitor app), "self-reported" (you entered the value manually, such as describing your ball flight pattern), or "derived" (the value was calculated from other measured values using a known formula). Each label tells you exactly how the value was produced so you can assess its reliability appropriately.

- Heuristic DataHeuristic data is information read through encoded expert rules of thumb to surface the most likely pattern quickly and reliably. This means a confident estimate, not a measured result.
- Confidence ScoreA 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.
- Data Source LabelA Data Source Label is the badge shown alongside every metric in SwingVantage that identifies where that data came from. This means Measured, Estimated, AI Interpreted, Placeholder, or Real. This means. As a result, you always know how to weight it.
- Measured ValueA measured value is a number that came from a real sensor or instrument. This means a launch monitor, radar gun, or wearable. This means and was not inferred or estimated from video or rules.
