Analysis Concepts Glossary
Plain-English definitions of how SwingVantage reads your swing — honest, explainable, and free.
28 terms
- Analysis JobIntermediateAn Analysis Job is the record SwingVantage keeps of each analysis run. It tracks the run's status, such as running, completed or failed, along with timings and a coarse confidence.
- BenchmarkIntermediateA benchmark is a reference value that defines acceptable or optimal performance for a metric; SwingVantage score outputs use one fixed pro grading standard.
- Blocked PracticeIntermediateBlocked practice is repeating the same skill or shot in the same conditions many times in a row. It is effective for initial skill acquisition but often less effective for long-term retention than varied practice.
- Consistency ScoreIntermediateA consistency score measures how tightly grouped your metrics are across multiple swings — low variance produces a high score. This is because consistency is often more valuable than peak performance.
- Deliberate PracticeIntermediateDeliberate practice is focused, feedback-rich work on a specific, diagnosed weakness. Unlike mere repetition or play, it tends to produce faster skill gains per hour of effort.
- Drill ProgressionIntermediateA drill progression is an ordered series of drills, from slow, controlled, isolated moves to full-speed, game-like play. It follows a common motor-learning approach.
- Frame RateIntermediateFrame rate (frames per second, fps) is how many individual images your camera captures each second — higher frame rates freeze fast motion better and produce more reliable pose tracking.
- Heuristic DataIntermediateHeuristic data is a confident estimate, not a measurement. Expert rules of thumb read the inputs and surface the most likely pattern quickly and reliably.
- Heuristic EngineIntermediateThe heuristic engine is the deterministic, rules-based part of SwingVantage that runs first on every analysis — no external AI call required.
- Improvement DeltaIntermediateAn improvement delta is the measured change in a metric from your baseline to your most recent measurement. It is the hard number behind "did I get better?"
- Interpreted ValueIntermediateAn interpreted value is a judgment drawn from indirect evidence, like 'likely timing issue' or 'probable hip stall'. It is not a direct measurement, and SwingVantage labels it Inferred.
- Kinematic ChainIntermediateThe kinematic chain is the order in which body segments, from the ground up, pass force and speed through a swing. Each segment hands its speed on to the next.
- Landmark TrackingIntermediateLandmark tracking follows the position of each detected body keypoint across consecutive video frames. This creates a time-series trajectory for every joint that enables timing and velocity measurements.
- Mobile Motion CaptureIntermediateMobile motion capture is the process of using a smartphone camera and on-device pose estimation to track body movement in real time or from a recorded clip — no specialized hardware required.
- Motor LearningIntermediateMotor learning is the science of how the nervous system learns, refines, and retains skilled movement. It explains how practice actually changes your swing.
- Outlier in Swing DataIntermediateAn outlier is a data point that falls far outside the normal range for that metric and session. It may represent a genuine extreme swing or a measurement artifact. It requires honest handling before being used in averages.
- Pose EstimationIntermediatePose estimation is the computer-vision process that detects the positions of major body joints (keypoints) in each video frame. This produces the skeleton that SwingVantage uses to measure angles and movement patterns.
- Primary vs. Secondary FaultIntermediateThe primary fault is the swing issue with the highest severity and impact on performance; the secondary fault is the most likely co-existing issue.
- Random PracticeIntermediateRandom (or variable) practice mixes skills, shots, or conditions in a session. Studies often find it beats blocked repetition for long-term retention and transfer to real play.
- Recommendation EngineIntermediateThe recommendation engine ranks possible fixes by impact and confidence so you get one high-leverage priority fix — not twenty competing tips.
- Recovery SessionIntermediateA recovery session is a low-intensity practice day focused on reinforcing patterns at slow speed, flushing fatigue, and keeping motor grooves active without accumulating more load.
- Retest DeltaIntermediateA retest delta is the change from your pre-drill baseline to your post-drill retest, on the metric your fix targeted. It shows if one session moved the needle.
- Rules EngineIntermediateThe rules engine is the core that checks your shot data and symptoms against sport-specific target windows to find the best-fitting pattern.
- Sample SizeIntermediateSample size is how many swings or shots a metric is based on — small samples produce more noise and lower confidence. Larger samples produce more reliable estimates.
- SeverityIntermediateSeverity is how much a swing fault is expected to cost you in performance. SwingVantage shows it as a priority label, such as High priority, and Motion Lab adds a Fix or Watch status.
- Signal vs NoiseIntermediateSignal is the real, repeatable pattern in your swing data; noise is the random variation that looks like a pattern but isn't. Distinguishing the two is what separates useful analysis from false precision.
- Skill AcquisitionIntermediateSkill acquisition is how practice and feedback make a movement more automatic, consistent, and robust under pressure. It is the goal of all training.
- Stability vs MobilityIntermediateStability vs mobility is the principle that joints alternate roles: some are stable anchors, others mobile movers. Faults often come from reversing these roles.
