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

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: 0.038 (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 sheet of concentric arcs echoes R3 but is thinner: the black arc is flat inside, the layering is simple, the upper left is weak, and drips mark the black arc's top edge. An ordinary, working sheet.”

Form · BUILT

Concentric arcs hold and follow the brush's travel; the dark arc's top end is cut square, and the pale left arcs dissolve into soft, loose edges.

WEAKEST Blunt squared top end of dark arc with drips

STRONGEST Mid-grey arc sweeping into dry-brush tail

Tonal depth · MODELLED

Grey bands show bristle streaks and graded tone; the measured dark-interior modulation is under the flat threshold, with only faint banding in the black arc; three tonal steps.

WEAKEST Dark arc interior largely flat (modulation 0.038)

STRONGEST Grey arcs streaked with bristle grain and arcs

Layering · LEGIBLE

Pale, mid-grey and black arc passes overlap translucently and stay readable, but the order is simple and the overlaps add little depth.

WEAKEST Pale left arcs barely register as a pass

STRONGEST Black arc laid over the mid-grey band, legible

Composition · WORKING

The rotating arcs give a strong clockwise direction and the lower-left void is shaped; the upper left is pale and weak, and the weight is crowded right.

WEAKEST Washed-out upper-left quarter

STRONGEST Sweeping spiral carrying eye to lower right

Material and surface · FLAWED

Small runs and blots sit on the top edge of the black arc, drops trail below the grey arc at centre-left, crease lines cross the grey bands, and there are bluish spots at the right edge.

WEAKEST Drips and blots at top of black arc

STRONGEST Dry-brush grain in grey arc tail

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, 17 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: 3 principal ink masses traced (cyan), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 19 edge segments, 32% crisp, 47% soft or bloomed, 21% broken.

RULE 1Two tonal steps or fewer

Tonal depth held at rung 1.

3 steps: not applied
RULE 2A major flaw

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

RULE 3Any quality below 0.5

lowest 1.6
RULE 4At least two valid reads

A read that breaks the reply format is discarded.

THE ARITHMETIC

V23 rating 6.3.

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.
