Analysis Concepts Glossary
Plain-English definitions of how SwingVantage reads your swing — honest, explainable, and free.
28 terms
- Analysis JobIntermediateAn Analysis Job is the traceable processing record created each time you submit a video or session for analysis — it tracks status (queued, running, complete, failed), the inputs used, and the outputs produced.
- 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 — effective for initial skill acquisition but 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 — distinct from mere repetition or play — that produces faster skill gains per hour of effort.
- Drill ProgressionIntermediateA drill progression is an ordered sequence of practice exercises that move from isolated, slow, and controlled movements toward full-speed, contextual performance — matching how motor learning actually works.
- 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 information read through encoded expert rules of thumb to surface the most likely pattern quickly and reliably — a confident estimate, not a measured result.
- 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 difference between a baseline value and the most recent measurement for the same metric. The hard number behind "did I get better?"
- Interpreted ValueIntermediateAn 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.
- Kinematic ChainIntermediateThe kinematic chain is the sequence of body segments — from ground to tip — through which force and speed are transferred in a swing, with each segment's energy amplifying 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 scientific study of how the nervous system acquires, refines, and retains skilled movement. The theory underlying 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 different skills, shot types, or conditions within a session — producing better long-term retention and transfer to real play than blocked repetition.
- 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 between a pre-drill baseline and the post-drill retest measurement for the same specific metric targeted by that session's fix — the short-cycle confirmation of whether a single training session moved the needle.
- Rules EngineIntermediateThe rules engine is the configuration-driven core that checks your shot data and symptoms against sport-specific target windows to identify 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 significant a swing fault is expected to be for performance, labeled Critical, High, Moderate, or Low.
- 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 the process by which practice and feedback cause a movement pattern to become more automatic, consistent, and robust under pressure — the goal of all training.
- Stability vs MobilityIntermediateStability vs mobility is the biomechanical principle that joints alternate between roles. Some must be stable anchors, others must be mobile movers — and faults often come from reversing these roles.
