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.

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.
