Plain-English definitions of how SwingVantage reads your swing — honest, explainable, and free.
65 terms
- AI Swing ReportBeginnerThe AI Swing Report is the report SwingVantage builds after analyzing your video. It leads with the engine's main finding and One Fix, with any optional AI-written coaching layered on top.
- AI-Enhanced AnalysisBeginnerAI-Enhanced Analysis is the optional AI layer on top of SwingVantage's rule-based result. It can rephrase the explanation in plainer coaching language, and an AI Vision Review can add a separate second read.
- 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.
- BalanceBeginnerBalance is the ability to keep a stable base and a controlled center of mass in a swing. It spans the full motion, from setup through the end of the follow-through.
- Baseline MeasurementBeginnerA baseline measurement is the first recorded data point for a metric, captured before training begins, that all future improvement is measured against.
- 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.
- Camera Angle QualityBeginnerCamera angle quality describes how well the recording position lets the system see the relevant joints and movement plane. It is one of the biggest factors you control in analysis accuracy.
- Confidence ScoreBeginnerA confidence score rates how much to trust a finding, based on how much good evidence supports it. SwingVantage shows it as a word, such as High, Moderate, or Low, rather than a number.
- 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.
- Data Source LabelBeginnerA data source label is the word beside a number or result that says where it came from or how it was worked out. It tells you how much weight to give that value.
- 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.
- Deterministic IntelligenceBeginnerDeterministic intelligence is analysis that follows explicit, written rules. The same inputs always produce the same answer, and you can trace exactly why.
- Diagnostic ConfidenceBeginnerDiagnostic confidence is how certain SwingVantage is about a finding. It depends on how much data was available and how reliably the pattern appears.
- 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.
- Estimated ValueBeginnerAn 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.
- Evidence LabelBeginnerAn evidence label separates what SwingVantage measured with a sensor or launch monitor from what it estimated. Estimates are never shown as lab measurements.
- 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.
- Ground Reaction ForceAdvancedGround Reaction Force (GRF) is the force the ground pushes back against an athlete's feet. It is the foundational energy input for the kinematic chain in every swing sport.
- Heuristic AnalysisBeginnerHeuristic analysis is smart, rules-and-pattern-based analysis that reads observable cues to surface what is most likely happening in your swing — a confident, data-backed estimate, not a guess.
- 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?"
- Instant EstimateBeginnerAn Instant Estimate is a fast, rules-only read built from your answers, such as your sport, usual miss and level, without needing a video. It is labeled as a lower-confidence estimate.
- 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.
- Lighting ConditionsBeginnerLighting conditions describe how evenly and brightly the subject is illuminated — poor lighting is one of the top causes of low-quality video and degraded pose estimation.
- Measured ValueBeginnerA measured value comes from a real sensor or instrument, like a launch monitor, radar gun, or wearable. It is not inferred or estimated from video or rules.
- 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.
- Mock / Demo DataBeginnerMock or demo data is example data used to show how a feature works, in demos, sample reports and previews. SwingVantage labels it Sample so it is not mistaken for real athlete data.
- Motion LabBeginnerMotion Lab is where SwingVantage analyzes your swing video, right in your browser. It tracks your body, grades the clip and leads you to one thing to work on, with a 3D view you can rotate and scrub.
- 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.
- Movement SequencingAdvancedMovement sequencing is the timed order in which body segments accelerate and decelerate through a swing — correct sequencing multiplies speed; incorrect sequencing bleeds it.
- One-Fix PlanBeginnerThe One-Fix Plan is SwingVantage's core methodology: identify the single highest-impact fault, build a focused practice plan around fixing only that fault, and confirm the fix with a structured retest before moving on.
- 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.
- Phone Video LimitationsBeginnerPhone video limitations are the practical constraints of recording on a smartphone. They can reduce analysis accuracy compared with purpose-built cameras.
- Placeholder DataBeginnerPlaceholder data is a stand-in shown where real data is not available yet. SwingVantage labels it so it is never mistaken for a measurement or an estimate.
- Player ProfileBeginnerThe Player Profile is the persistent record of an athlete's sport, skill level, swing history, fault patterns, progress metrics, and linked sessions that SwingVantage uses to personalize your coaching and recommendations.
- 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.
- Practice PlanBeginnerA practice plan is a structured, time-blocked schedule of drills and tasks designed to address your diagnosed fault with the right repetitions, feedback cues, and retest protocol.
- Practice TransferAdvancedPractice transfer is how much a skill learned in a practice environment carries over to real performance — the ultimate measure of whether your training actually worked.
- 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.
- Progress TrackingBeginnerProgress tracking is the longitudinal record of how your key metrics change over multiple sessions and retests, displayed as a timeline that shows improvement, plateaus, and regressions.
- 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.
- Real / Live DataBeginnerReal data comes from an actual recording, device or session, not from a placeholder or an example. On the source labels, Real marks a value that is a true measurement rather than an estimate or example data.
- 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.
- RetestBeginnerA retest is a short follow-up protocol attached to each recommendation. It says how to repeat the test, what to compare, and what success looks like, so you can see whether a fix worked.
- 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.
- Skeleton OverlayBeginnerA skeleton overlay draws your detected body joints, and the lines connecting them, over your video. It shows exactly what the system tracked.
- 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.
- Skill TreeBeginnerThe Skill Tree is a map of a sport's key technical skills. It shows which skills your sessions give evidence for, which are improving, and which come later at your level.
- 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.
- Swing DecodeBeginnerSwing Decode is the contact read inside Motion Lab results. It focuses on the moment of contact and shows the path, plane and timing reads your clip supports.
- TempoBeginnerTempo is the timing relationship between the two halves of a swing — the rhythm that separates efficient, repeatable mechanics from a rushed or laboured transition.
