This rating is mostly the starting prior, not this surfer. He has 12 rated heats, below the 16-heat threshold at which a surfer's own record outweighs the prior — 57% of the figure below is still the prior every surfer starts at. 35 of the 73 rated surfers are in the same position, which is why the leaderboard filters them out by default rather than ranking them.

Reading it — the line is Trim after each heat: points per heat above or below what that round usually yields. It starts at the prior, 0.000, and moves by a decayed share of each heat's deviation. The bars below are those deviations, one per heat, on their own scale. Neither panel is a prediction.

Extremes — best +2.55 at 2024 Hurley Pro Sunset Beach · Opening Round heat 9; worst −6.57 at 2025 Lexus Pipe Pro · Elimination Round heat 1. Axis to ±7, the exact maximum rounded outward.

How this is computed
Computed over trim joined to datum, in the run's own ordering — 12 of this surfer's 12 heats. Trim is an EWMA of the deviation from Datum (ewma_residual_hl15, half-life 15 heats, prior 0, computed 2026-10-17 over 1845 entries and 73 surfers). Datum is a ridge on the round alone, so “expected” is what that round usually yields, not what these conditions or this break usually yield. The decay earns very little: walk-forward RMSE 2.9098 against 2.9123 for a shrunk flat mean of the same residuals — paired t 0.56. Predicting zero for everyone scores 2.9688. The ordering is what Trim is for; the half-life is not doing the work.

How this is computed
Computed over heat_entries joined to heats, rounds and events, one row per heat surfed. position and heat_total are published, never derived from the rides; a heat with no total renders as an em-dash, never as zero. The counting rides are the stored waves.counted flag in score order, not ride order, which is how WSL publishes the decomposition; they are not the best two, because an interference penalty zeroes a counting ride without promoting the next one. counting_rides belongs to the round, not the event. Venue is heats.venue_id — the break the heat was actually surfed at, which for 11 of these 12 heatsis stored, and which is not always the event's nominal venue. Round order carries a known gap and no tie countback is stored, so a shared position is shown as published.

What these are not Conditions are not in the model. Datum V1 is a ridge on the round alone: break, wave type and field size were tested on 27 August and dropped, because adding them made the leave-one-event-out error worse rather than better. The “vs Datum” column in each split is therefore this surfer's deviation from what that round usually yields, averaged over the heats that fall in the split. It is a description of where he scored, not a measurement of conditions he favours, and a difference between two rows here is not evidence that either caused anything. Computed over the 12 of his 12 heatswhose popup was retained and publishes both figures; the remainder are absent from these tables rather than pooled into an “unknown” row.

How this is computed
Computed over heats.wave_height_published and heats.wind_conditions, both read off the retained heat popup and shown in the words the page used. Across the database these are held for 771 of 801 heats, a different population from venue, which is held for 713. For this surfer that is 12 of 12. Heats with no published conditions are left out of both tables; they are not an “unknown” category.
