Every value below comes from vae.db, the master database of the Crucible Year. ## Recorded - **Date:** 2026.11.03, day 310 - **Size:** 97 × 180 cm - **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper, self-sized - **Inks:** MB6, MB8, MB9, MB10 - **Phase:** P4 S14 - **Shown on the site:** yes (combined score of 5.0 or more) ## The combined score - **Combined score:** 6.14 - **Read half:** 30 - **Measured half:** 31.4 The rating shown on a work page, out of 10: V23's rating times 5, plus V24's twelve tests of 50, divided by 10. 5.0 on it decides what the site shows, and it is read here at two decimals for that reason. [How it is built](https://peteryuill.art/method#combined). ## Read · V23 (v23.13) - **V23 rating:** 6 - **Form:** 2 - **Tonal depth:** 1.8 - **Layering:** 2.2 - **Composition:** 2.2 - **Material and surface:** 2 - **Ink cover:** 76% - **Dark share:** 67% - **Tonal steps:** 3 - **Flaws named by the reads:** other 16, water stain 3, tide line 4, ring 2 The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the model's reading held by code's rules, and the read half of the combined score. Where Peter reviewed a run, this is the reviewed figure. ## Measured · V24, from the 16-bit TIFF - **Mass:** 9.4 of 10 - **Tone:** 10.4 of 14 - **Void:** 6.4 of 8 - **Flow:** 5.2 of 10 - **Balance:** 0 of 8 - **Measured half:** 31.4 of 50 - **Mass width in mm:** rung 5 of 5 - **Mass width against the sheet:** rung 5 of 5 - **Evenness of that width:** rung 4 of 5 - **Depth of the darks:** rung 4 of 5 - **Black plateau:** rung 4 of 5 - **Step from mid to dark:** rung 3 of 5 - **Evenness inside the darks:** rung 4 of 5 - **Spread across tonal bands:** rung 3 of 5 - **Voids gathered, not scattered:** rung 4 of 5 - **Directions across the sheet:** rung 1 of 5 - **Local gesture and edge:** rung 5 of 5 - **Balance on the sheet:** rung 0 of 5 - **Mass width:** 281 mm - **Depth of the darks (p75 density):** 1.79 - **Largest void, radius:** 220 mm - **Direction alignment:** 0.40 - **Left and right asymmetry:** 1.26 - **Resolution:** 3.91 px per mm Twelve deterministic tests with no model and no votes. They track physical change across the year and cannot see a mark's quality, so they are no verdict on one work. [The tests and their limits](https://peteryuill.art/method#measured). ## How the number was made Read by the Visual Analysis Engine, version 23.13, on 2026.11.03: measured by code, then read 5 times by Claude Opus 5.5 against three reference paintings (R1 to R3), each read independent of the others. [How the engine works](https://peteryuill.art/method). WHAT THE CODE SEES ## Three views of one sheet. Left, the photograph. Centre, the tone stretch the model is shown beside it: the darkest 45% of tones spread over the whole range, so flat black, banding and stains show. Right, every pixel as the measuring code classes it: cyan black ink, deep teal translucent grey, stone the palest ink, near black bare paper. ![T_412] ![T_412, tone-stretched] ![T_412, classed by brightness] 76% of the sheet carries ink TONAL STEPS ## 3 families of tone. Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Life inside the black: 0.054 (under 0.045 reads as flat). FIVE READS ## Five reads, agreeing on 2 of 5 qualities. Each quality placed on its ladder by each read, and the mean the engine keeps. Where reads differ, they differ by one rung; close calls resolve down.

Ordered layering is its best quality; otherwise an ordinary, working sheet.” Form · BUILT Two arc-segment masses have coherent, holding walls following a curved sweep, but the black cores read as filled slabs; stepped joins lower left of the right mass are stiff. WEAKEST Bulky black fan core with clumsy stepped notches, upper right STRONGEST Outer arc band sweeping beneath the upper right mass Tonal depth · MODELLED Grey bands show grain and stepped density; black cores read almost flat in colour, with only faint variation when stretched. Modulation 0.054 sits just above the flat line. WEAKEST Lower left black core, nearly flat inside STRONGEST Grey arc bands with grain, lower right and lower left Layering · ORDERED Pale dry-brush, grey, darker grey and black passes step in clear order on both masses; overlaps at the right arc and lower left edge stay readable and build depth. WEAKEST Opaque black cores conceal the passes beneath them STRONGEST Stepped translucent bands around the upper right fan Composition · WORKING Opposed arcs imply one large circular sweep, with a shaped diagonal channel between them, but the black mass sits heavy and the top left paper does little work. WEAKEST Heavy black upper right mass dominates; top left paper is passive STRONGEST Diagonal white channel between the two opposing arcs Material and surface · SOUND Ink is controlled and edges bind cleanly; dry-brush is good but not form-shaping throughout. Small creases in the black and grey bands, plus faint cloudy wash low centre, remain minor. WEAKEST Crease marks in the right of the black mass STRONGEST Dry-brush drag in pale arcs, centre of sheet FLAWS ## 4 distinct places, 0 major. Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 4 distinct places, 25 mentions in all across 5 reads; the number in each ninth is how many times a flaw was named there. Reads agreeing on a place strengthen the evidence for one flaw; they do not multiply it. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 3 steps: not applied RULE 2 A major flaw Material held at rung 1. Mild waves in the unmounted paper are never a flaw. none named RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 1.8 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid THE ARITHMETIC ## V23 rating 6.0. Engine v23.13, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on a stratified sample of 24 paintings so the median sheet scores 5. The scale is relative to this archive, not to painting in general, and a difference of less than half a point between two paintings is noise.
