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
9
Peter's rating is his own eye, not the engine's, and he never gives a 10.

Older engine

V10C
9
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

5 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: 0.056 (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.

READ 1, IN ITS OWN WORDS

“This is a radial arc vortex close in kind to R3, with fluent bands and legible translucent layering. It is denser and heavier than R3, the lower-right blacks are fairly flat, and the paper has little room to breathe.”

Form · FLUENT

Radial arc bands everywhere follow the brush's sweep, with dry-brush ends on the bands at upper right; the blunt left-edge block is minor.

WEAKEST Squared-off dark block at far left edge

STRONGEST Inner curling arcs hugging the white central void

Tonal depth · MODELLED

Five tonal steps; greys from pale wash to black. Tone-stretched view shows grain and veining in most masses, but the lower-right blacks stay heavy and nearly uniform.

WEAKEST Lower-right black band, near-flat interior

STRONGEST Upper-right dark arc with grain and veining

Layering · ORDERED

Many translucent arc passes overlap in readable sequence, especially at left and upper right. The pale outer washes sit under the darker inner bands.

WEAKEST Right-side darks stacked so deep that order blurs

STRONGEST Left fan of translucent grey arcs overlapping

Composition · WORKING

The radial vortex pulls the eye to the white centre at the bottom, but 85% ink coverage leaves little breathing paper, and the right half is dense and weighty.

WEAKEST Crowded heavy dark mass filling lower right

STRONGEST White central void with the arcs swinging around it

Material and surface · SOUND

Ink is controlled with clean arc edges. A fine crackle network runs through the dark masses, legible as texture. There are no tide lines or rings.

WEAKEST Crackle crease lines across dark interiors

STRONGEST Dry-brush band ends at upper right

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, 11 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: 2 principal ink masses traced (cyan), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 20 edge segments, 40% crisp, 45% soft or bloomed, 15% broken.

THE ARITHMETIC

V23 rating 8.0.

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.
