The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the engine's reading, and the reference the archive is measured against.

Older engine

V7
5
From an earlier engine (V7). Its scale differs from V23's, so it is only ever compared with other readings by the same engine.

How the number was made

Read by the Visual Analysis Engine, version 23.8, on 2026.10.06: 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.

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.

TONAL STEPS

6 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: 0.061 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“This gestural sheet is close to R2. Grey passes stay legible and a diagonal sweep links the left fan to the right V. Scattered ringed water stains, a ragged left blot and a flat black core hold it at ordinary or below.”

Form · BUILT

Right dark V and top-right mass read as made strokes with travel; left dark patch is a ragged blob; the central diagonal sweep holds.

WEAKEST Left dark blot, ragged and lobed

STRONGEST Right V-shaped dark stroke with splayed edges

Tonal depth · MODELLED

Six tonal steps; the grey washes show grain and banding at left and centre, but the black core at top right is dense and flat.

WEAKEST Top-right black core flat inside

STRONGEST Left grey fan with granulated banding

Layering · LEGIBLE

Several translucent grey passes overlap at left and right and stay readable; black passes sit on top, and the order blurs in the right cluster.

WEAKEST Right washes muddled under the dark V

STRONGEST Translucent grey planes overlapping at left

Composition · WORKING

Two masses joined by a rising diagonal give direction; the top-centre and lower-centre paper is cluttered with drops and lacks shape.

WEAKEST Centre-bottom spatter field feels leftover

STRONGEST Diagonal sweep linking left fan to right V

Material and surface · FLAWED

Many pale ringed blots with tide edges scattered across centre and top-centre; a vertical drip trail at lower centre; milky cloudy wash at left.

WEAKEST Ringed droplet stains across the centre

STRONGEST Dry-brush streaks at right edge washes

FLAWS

5 distinct places, 2 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 5 distinct places, 20 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. A major flaw holds Material and surface at rung 1.

GEOMETRY

Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 1 principal ink mass traced (cyan), 5 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 17 edge segments, 35% crisp, 35% soft or bloomed, 29% broken.

Tonal depth held at rung 1.

6 steps: not applied
RULE 2A major flaw

Material held at rung 1. Mild waves in the unmounted paper are never a flaw.

A read that breaks the reply format is discarded.

THE ARITHMETIC

V23 rating 5.0.

Engine v23.8, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on 24 randomly chosen 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.
