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.

Peter's own rating

Rating
8
Peter's rating is his own eye, not the engine's, and he never gives a 10.

Older engine

V10C
7
From an earlier engine (V10C). 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

4 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: 0.044 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 3 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.

READ 1, IN ITS OWN WORDS

“A concentric-arc sheet close to R3: the arcs are fluent, the translucent passes are layered in a clear order and the rotation is strong. The black masses are flat inside, and there are small marks on the blank paper.”

Form · FLUENT

Concentric arc strokes follow brush travel with dry-brush trailing edges; right-hand block cluster is more rectilinear but its strokes still read as made, with no clumsy joins.

WEAKEST Right cluster of stiff stepped rectangular blocks

STRONGEST Large black arc sweeping from top to centre

Tonal depth · MODELLED

Measured dark modulation 0.044 is flat; black arc and right black block are uniform inside. Grey bands show crackle, grain and stepped density, giving four tonal plateaus.

WEAKEST Interior of the main black arc band

STRONGEST Stepped grey arcs in lower-left quarter

Layering · ORDERED

Several translucent grey arc passes overlap in readable order beneath the black; the stepped segments build depth from the outer pale rings inwards to the black.

WEAKEST Black block in right cluster covers earlier greys

STRONGEST Overlapping translucent arc segments lower left

Composition · COMMANDING

Large arc wheels the eye from top-left around to bottom; empty circular void top-centre is shaped and active; right cluster echoes the rotation and counters the mass.

WEAKEST Bottom-left edge, crowded with pale arcs

STRONGEST Open curved void at top centre

Material and surface · SOUND

Ink controlled with dry-brush edges; small blot lower right and grey specks in top-right paper sit away from principal masses; crackle texture in greys reads as paper character.

WEAKEST Stray ink blot near lower right edge

STRONGEST Dry-brush trailing edge on black arc

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, 15 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.

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 15 edge segments, 53% crisp, 40% soft or bloomed, 7% broken.

THE ARITHMETIC

V23 rating 7.3.

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.
