What you get
A full benchmark tracker.
500 m, 1 k, 2 k, 5 k, 6 k, 10 k, 30 min, 60 min — pulled from your fastest efforts across the history you upload. Extrapolated benchmarks are flagged, never faked.
Your Concept2 world-ranking percentile.
Age × weight × sex bracket, using the official Concept2 world-ranking data. If we don't have your age or weight, the report says "unranked bracket" rather than making something up.
Split, watts and stroke-rate trends.
90-day median trends with an IQR band, cleaned of sessions with missing HR or watts data. Direction only appears when there are enough sessions to say so honestly.

FAQ
Do you keep my data?
Not unless you choose to. Anonymous uploads are processed in your browser and discarded when you close the tab. Signed-in users can save derived reports; raw files are never stored.
Does the percentile use my exact age?
Percentiles are bucketed into standard Concept2 age bands (19-29, 30-39, 40-49, 50-59, 60-69, 70+). Bring your age, sex and weight for an accurate bracket.
