Most swimming platforms treat a Personal Best (PB) as the only metric of success. MyAthlete's Performance Engine deconstructs every swim to provide a forensic view of an athlete’s reliability, volatility, and competitive standing.
1. Individual Swim Metrics
Every time a result enters the database, the engine calculates a series of proprietary metrics to answer the question: "Taking into account my history and recent form, how good was this specific performance?"
- Benchmark Improvements: The raw time difference (in seconds) between the current swim and the athlete's Lifetime PB, Season Best (SB), and their most recent swim.
- LPBCS (Lifetime PB Closeness Score): A score from 0 to 100 measuring how close a swim was to the athlete's peak PB at that time. A high LPBCS (e.g., 95+) indicates high Reliability—the athlete consistently performs near their peak, even if they don't set a new PB every time they dive in.
- Swim Score: The definitive composite score (0-100) that weights the athlete's performance against their PB (weighted 2x), their SB, and their most recent time.
- FINA Points: The international standard scoring system allowing for cross-event comparison (e.g., comparing the quality of a 100m Free against a 200m Breaststroke).
2. Event Trend Analysis
To analyze long-term trends for a specific event (e.g., "100m Freestyle SCM"), MyAthlete filters out multi-round noise by using the fastest swim per competition to calculate the following macro-metrics:
| Metric | Definition | Coach's Interpretation |
|---|---|---|
| PCI (Positive Change Index) | % of swims equal to or faster than the preceding swim. | Improvement Frequency. A PCI of 75% means they get faster 3 out of every 4 times they race. |
| PBIR (PB Improvement Rate) | % of swims that resulted in a new Lifetime PB. | Breakthrough Frequency. Identifies when an athlete has entered a high-growth phase. |
| MAD (Mean Absolute Deviation) | The percentage fluctuation between consecutive swims. | Stability. Low MAD (<1%) is typical of highly technical, reliable swimmers. High MAD (>3%) indicates erratic form or technical changes. |
| AMPC (Avg. Monthly % Change) | The average rate of improvement per month. | Progression Velocity. The slope of the improvement curve. A -0.5% AMPC is solid, steady growth. |
3. FpM6 & Squad Aggregation (The Coach's View)
For Head Coaches, understanding the trajectory of the entire club requires filtering out the noise of new beginners joining the squad.
The FpM6 Power Rating
The Top Performance Index (FpM6) is a power rating based on the moving average of an athlete's Top 5 FINA scores within a quarter. By averaging the top 5, it removes one-off "flukes" to reveal the athlete's true, established competitive ceiling. Tracking FpM6 Growth is the ultimate metric to see if an athlete is actually leveling up.
The "Top 10% + 10" Aggregation Rule
When a coach views Squad or Club analytics, MyAthlete does not use a simple average (which would dilute the score if 20 new beginners joined). Instead, the system calculates the average of the Top 10% of athletes plus the next 10 most successful athletes.
This measures the Standard of Excellence. It shows the coach exactly how their "Leading Edge" is performing, protecting the integrity of the data as the club grows.
4. AI Predictions & Equivalent Conversions
Moving beyond historical tracking, MyAthlete provides advanced tools to forecast the future and translate environments.
Predict AI
Our bespoke Machine Learning engine answers the question: "What will I swim in 6 months?" The model is trained on hundreds of thousands of historical swims. It processes an athlete's proprietary MyAthlete metrics, age, stroke, and distance to output a predicted time with a Confidence Range (e.g., "1:02.4 - 1:04.1"), allowing for highly accurate, data-backed goal setting.
The "Convert" Service (SPORTSYSTEMS)
When athletes need to translate a 25m Short Course (SCM) time to a 50m Long Course (LCM) or 25y Yards (SCY) pool, MyAthlete uses the industry-leading SPORTSYSTEMS algorithm. This is not a rough percentage shift; it is a complex quadratic calculation that accounts for:
- Turn Factors: The exact time gained or lost pushing off a wall, specific to the biomechanics of each stroke.
- Pool Measure Factors: Precise distance adjustments required when moving between Metric and Imperial pools.
5. Club Records Governance
MyAthlete automates the identification of "Club Records" using strict governance policies to ensure undisputed accuracy:
- Representation Check: A swim only qualifies as a record if the athlete was officially representing your club at that specific meet.
- The Open Policy: Records are tracked by Age Group (Junior/Senior). However, if a 15-year-old sets a time faster than the Senior record, the system automatically credits them with both the Junior and the "Open" (Senior) record.
