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
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.

TONAL STEPS

7 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: 0.047 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 4 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 close sibling of R3, with two fans of stacked translucent arcs around a central opening. The layering is ordered and the composition is strong. The dark interiors are only slightly modelled, and there is one tiny flaw at the bottom left.”

Form · FLUENT

Concentric arc bands on both halves follow the brush's sweep with crisp squared ends; only the bottom-left stub reads slightly blocky.

WEAKEST Squat dark stub block at bottom-left edge

STRONGEST Inner small arc ring around central opening

Tonal depth · MODELLED

Greys carry grain and banding, seven tonal steps; but dark interior modulation 0.047 is barely above flat, right black mass reads mostly solid.

WEAKEST Right central black arc mass, nearly uniform interior

STRONGEST Left grey bands with grain and crackle texture

Layering · ORDERED

Many translucent arc passes stacked outward from pale to dark, overlaps legible and ordered on both halves; right dark core loses some separation.

WEAKEST Right dark passes merge into near-solid block

STRONGEST Stepped translucent outer arcs, upper left

Composition · COMMANDING

Two arc fans radiate around a central opening, the white gap and paper above shaped and active; eye swings along the arcs across the sheet.

WEAKEST Bottom-left corner crowded by stub block

STRONGEST Central vertical gap splitting two arc fans

Material and surface · FINE

Grain, dry-brush stroke ends and crackle texture shape the bands; only a tiny white notch bottom-left and small speck at right edge.

WEAKEST Small torn white notch in bottom-left dark

STRONGEST Dry-brush squared ends on upper grey bands

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, 12 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 17 edge segments, 24% crisp, 65% soft or bloomed, 12% broken.

THE ARITHMETIC

V23 rating 8.5.

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.
