Methodology
How every score is actually calculated.
No black box. Every number a coach or administrator sees in Athletic Advantage is built from a formula on this page.
Every score below is a wellness and workload-planning signal, not a medical assessment. None of them diagnose, treat or predict injury, and none replace professional medical advice.
Daily
Wellness Score
Built from the athlete's daily check-in — four short steps covering sleep and recovery, energy and hydration, a tap-based body soreness map, and general wellbeing (mood, stress, anything off). The answers combine into a single score from 0–100.
Range
0 – 100
When it's blank
No check-in submitted today — the Wellness Score stays blank rather than showing a fabricated zero or carrying over yesterday's number.
Daily
Training Drain
The total training load an athlete has logged today, across every session.
Per session
duration (min) × RPE (1–10) ÷ 20
Today's Training Drain
sum of every logged session's load, today
RPE is the athlete's own rating of perceived exertion for that session, from 1 (very easy) to 10 (maximal effort).
Daily
Recovery Boost
Points earned today from logged recovery activities — a small, capped credit toward the Recovery Score, not a separate score of its own.
Daily
Recovery Score
The headline daily number. Today's Wellness Score, adjusted down for training completed today and up for recovery work logged today, clamped to a 0–100 range.
Wellness Score − Training Drain + Recovery Boost
clamped to 0–100
If the Wellness Score is blank because no check-in was submitted, the Recovery Score is blank too — never estimated, never carried over from a previous day.
Rolling
ACWR — Acute:Chronic Workload Ratio
Compares an athlete's recent training load with their own longer-term baseline — a workload-planning guide, not an injury prediction.
Acute load
Sum of session load over the trailing 7 days
Chronic load
Average weekly session load over the trailing 28 days
Ratio
Acute load ÷ Chronic weekly load
Below 0.8
Lighter recent workload relative to baseline
0.8 – 1.5
Balanced range
Above 1.5
Flagged for coach review
A ratio only appears once there's enough logged history to make it meaningful — with sparse data, the athlete shows a "Building baseline" state instead of a number that would overstate its own confidence.
