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
6
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

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: 0.062 (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 strong layered arc on the right echoes R3. It is weakened by stiff, scattered marks on the left, a flat dark block, minor creases and a cloudy patch beside the arc.”

Form · BUILT

Right arcs follow the brush's travel fluently. Left-centre dark block is a blunt slab, and the far-left splash knot is lumpy; the walls hold but some marks are stiff.

WEAKEST Stiff dark rectangular slab, left-centre

STRONGEST Concentric arc bands sweeping around the right opening

Tonal depth · MODELLED

Arc interiors show banding, grain and graded density, with modulation 0.062. The dark rectangle and left knot have little internal variation, and tonal steps are only 3.

WEAKEST Dark left-centre block nearly flat inside

STRONGEST Arc bands with dry-brush grain and stepped greys

Layering · ORDERED

Successive arcs overlap translucently. Grey outer bands sit under the darker inner and top-right passes, so the order can be read and builds depth across the right half.

WEAKEST Left marks are essentially single passes

STRONGEST Overlapping translucent arc passes in the right mass

Composition · WORKING

The arc mass commands the right and leads inward. The left blocks and spatter feel scattered and weakly tied to it, and the upper-left paper reads partly as leftover.

WEAKEST Scattered left cluster and empty top-left paper

STRONGEST Arc spiral drawing the eye to the white opening

Material and surface · SOUND

Dry-brush grain is well used in the arcs. Fine crease or crack lines cross the dark arcs, and a pale grey cloudy patch sits at the arc's left edge, mid-height.

WEAKEST Crease lines and pale cloud beside arc

STRONGEST Dry-brush grain in the arc bands

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, 13 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: 6 principal ink masses traced (cyan), 2 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 25 edge segments, 52% crisp, 12% soft or bloomed, 36% broken.

THE ARITHMETIC

V23 rating 6.2.

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.
