Calculation method
Calculation method
Mean of largest ceil(N/3) waves (m)
Sort observed individual heights descending and average largest rounded-up third.
Individual-wave RMS height (m)
sqrt(mean(H²)); not spectral Hm0 without an elevation spectrum.
Maximum observed height (m)
Maximum supplied individual height.

Assumptions & limits
Assumptions & limits
- Observed wave heights, chosen statistic. Returns Top-third and spectral-style summaries as supported. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Individual observed wave heights (m): minimum 0, maximum 1000000000000.0.
