Measured Value
Also known as: measured data, sensor data
A measured value is a number that came from a real sensor or instrument — a launch monitor, radar gun, or wearable — and was not inferred or estimated from video or rules.
Measured values are the gold standard in SwingVantage's data provenance system. When you import data from a launch monitor (ball speed, spin rate, launch angle) or a radar device (pitch speed, serve speed), those values are labeled 'measured' throughout the app. They are the most trustworthy inputs because they were observed directly, not derived. The distinction matters: a measured ball speed of 152 mph is a fact; an estimated ball speed of 'likely around 150 mph' from video is an inference.
Example
A TrackMan session imported into SwingVantage shows ball speed as 'Measured — 157 mph' and spin rate as 'Measured — 2,680 rpm', neither subject to video estimation error.
Why it matters
Knowing a value was actually measured — not estimated — is the difference between acting on a fact and acting on an assumption. SwingVantage always tells you which.
Related terms
- Estimated ValueAn estimated value is a number derived from observable cues and encoded rules rather than from direct sensor measurement — a confident, grounded inference that is never presented as a measured fact.
- Interpreted ValueAn interpreted value is a judgment or label that emerged from AI reasoning applied to raw data — such as 'likely timing issue' or 'probable hip stall' — rather than from a direct measurement or a deterministic rule.
- Data Source LabelA Data Source Label is the badge shown alongside every metric in SwingVantage that identifies where that data came from — Measured, Estimated, AI Interpreted, Placeholder, or Real — so you always know how to weight it.
- Evidence LabelAn evidence label separates what SwingVantage measured (a sensor or launch-monitor number) from what it estimated (an inferred likely pattern), so an estimate is never presented as a lab measurement.
