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
8
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.

Black 55%Grey 40% SHARE OF THE INK, NOT OF THE SHEET
TONAL STEPS

2 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Two or fewer: Tonal depth is held at the bottom rung whatever the model reads. A dense sheet of many translucent passes can count low here, so Layering is left to the reads. Life inside the black: 0.029 (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

“Radial fan like R3 in idea, but denser and flatter: dark interiors are uniform, there are only two tone families, the right block is stiff and stepped, and the sheet is crowded. Surface sound.”

Form · BUILT

Left spiral arcs follow brush travel well; right-hand group ends in squared, stacked slab tops that read as stiff, bulky blocks.

WEAKEST Stepped blocky slab ends of right-hand fan

STRONGEST Curving arc bands spiralling into lower-left eye

Tonal depth · THIN

Measured dark interior modulation 0.029 (flat) and only two tonal plateaus; banding mostly at band edges, the big dark interiors read uniform.

WEAKEST Large dark mass centre-left, flat interior

STRONGEST Dry-brush streaking in arc near centre bottom

Layering · LEGIBLE

Many overlapping band edges remain readable at the fan rims, but the facts show two tone families; dark core passes merge into one tone.

WEAKEST Dense centre where overlaps converge into one dark

STRONGEST Translucent overlapping bands at outer fan edges

Composition · WORKING

Spiral gives clear movement toward the white hole; 84% coverage leaves only a top-right wedge of paper, and the right block sits heavy.

WEAKEST Crowded right half, little shaped empty paper

STRONGEST Spiral sweep leading into white eye, lower left

Material and surface · SOUND

Ink controlled overall; minor drops near lower-left eye, fine crease lines top-centre, specks top-right paper, none disrupting a principal mass.

WEAKEST Small spots and creases in paper, lower left

STRONGEST Dry-brush grain in central arc stroke

FLAWS

5 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 5 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), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 75% crisp, 25% soft or bloomed, 0% broken.

THE ARITHMETIC

V23 rating 5.2.

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.
