- Analysis JobIntermediateAn Analysis Job is the traceable processing record created each time you submit a video or session for analysis. This means it tracks status (queued, running, complete, failed), the inputs used. The outputs produced.Analysis Concepts
- BenchmarkIntermediateA benchmark is a reference value that defines acceptable or optimal performance for a given metric, used to judge your data against the right standard for your sport and skill level.Analysis Concepts
- Blocked PracticeIntermediateBlocked practice is repeating the same skill or shot in the same conditions many times in a row. This means effective for initial skill acquisition but less effective for long-term retention than varied practice.Analysis Concepts
- Consistency ScoreIntermediateA consistency score measures how tightly grouped your metrics are across multiple swings. This means low variance produces a high score. This is. This is because consistency is often more valuable than peak performance.Analysis Concepts
- Deliberate PracticeIntermediateDeliberate practice is focused, feedback-rich work on a specific, diagnosed weakness. This means distinct from mere repetition or play. This means that produces faster skill gains per hour of effort.Analysis Concepts
- Drill ProgressionIntermediateA drill progression is an ordered sequence of practice exercises that move from isolated, slow, and controlled movements toward full-speed, contextual performance. This means matching how motor learning actually works.Analysis Concepts
- Frame RateIntermediateFrame rate (frames per second, fps) is how many individual images your camera captures each second. This means higher frame rates freeze fast motion better and produce more reliable pose tracking.Analysis Concepts
- Heuristic DataIntermediateHeuristic data is information read through encoded expert rules of thumb to surface the most likely pattern quickly and reliably. This means a confident estimate, not a measured result.Analysis Concepts
- Heuristic EngineIntermediateThe heuristic engine is the deterministic, rules-based part of SwingVantage that runs first on every analysis — no external AI call required.Analysis Concepts
- Improvement DeltaIntermediateAn improvement delta is the measured difference between a baseline value and the most recent measurement for the same metric. This means the hard number behind "did I get better?"Analysis Concepts
- Interpreted ValueIntermediateAn interpreted value is a judgment or label that emerged from AI reasoning applied to raw data. This means such as 'likely timing issue' or 'probable hip stall'. Instead of from a direct measurement or a deterministic rule.Analysis Concepts
- Kinematic ChainIntermediateThe kinematic chain is the sequence of body segments. This comes from ground to tip. This means through which force and speed are transferred in a swing, with each segment's energy amplifying the next.Analysis Concepts
- 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.Analysis Concepts
- 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. This means no specialized hardware required.Analysis Concepts
- Motor LearningIntermediateMotor learning is the scientific study of how the nervous system acquires, refines, and retains skilled movement. This means the theory underlying how practice actually changes your swing.Analysis Concepts
- Outlier in Swing DataIntermediateAn outlier is a data point that falls far outside the normal range for that metric and session. This means it may represent a genuine extreme swing or a measurement artifact. It requires honest handling before being used in averages.Analysis Concepts
- 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.Analysis Concepts
- 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.Analysis Concepts
- Random PracticeIntermediateRandom (or variable) practice mixes different skills, shot types, or conditions within a session. This means producing better long-term retention and transfer to real play than blocked repetition.Analysis Concepts
- Recommendation EngineIntermediateThe advice engine ranks possible fixes by impact and confidence so you get one high-leverage priority fix — not twenty competing tips.Analysis Concepts
- 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.Analysis Concepts
- 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. This means the short-cycle confirmation of whether a single training session moved the needle.Analysis Concepts
- 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.Analysis Concepts
- Sample SizeIntermediateSample size is how many swings or shots a metric is based on. This means small samples produce more noise and lower confidence. Larger samples produce more reliable estimates.Analysis Concepts
- SeverityIntermediateSeverity is how significant a swing fault is expected to be for performance, labeled Critical, High, Moderate, or Low.Analysis Concepts
- 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.Analysis Concepts
- Skill AcquisitionIntermediateSkill acquisition is the process by which practice and feedback cause a movement pattern to become more automatic, consistent, and robust under pressure. This means the goal of all training.Analysis Concepts
- Stability vs MobilityIntermediateStability vs mobility is the biomechanical principle that joints alternate between roles. This means some must be stable anchors, others must be mobile movers. This means and faults often come from reversing these roles.Analysis Concepts
