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
10
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: 0.052 (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

“Close in kind to R3: radial fans of layered translucent arcs around a central void. The black blocks are blunter and flatter inside, and the sheet is more crowded, so it sits below R3.”

Form · BUILT

Arc bands hold their walls and follow curved travel, but the top-left and upper-right black blocks are bulky rectangles with stiff, squared joins.

WEAKEST Top-left black block, slab-like with blunt square ends

STRONGEST Lower-right curved black arc following the brush's sweep

Tonal depth · MODELLED

Grey bands show streaking and stepped density, and there are five tonal steps. Dark interior modulation of 0.052 is only just above flat; the big black masses read mostly flat.

WEAKEST Upper-right black block, nearly uniform inside

STRONGEST Lower-right grey arcs with banding and dry-brush grain

Layering · ORDERED

Several translucent grey passes overlap in a readable order across both fans. The overlaps build depth, and the edges stay legible where they cross.

WEAKEST Black slabs covering earlier greys at the top left

STRONGEST Stacked translucent arcs on the right, sequence readable

Composition · COMMANDING

Two radial fans converge on a shaped white opening at the bottom centre, carrying the eye inward. Ink covers 88% of the sheet, so the top feels a little crowded.

WEAKEST Crowded upper band where the fans nearly close

STRONGEST Central white void shaped by the two converging fans

Material and surface · SOUND

The ink is controlled with clean edges. Paper crease or crackle lines show through the grey arcs at bottom right and top centre, but they are minor and away from the black masses.

WEAKEST Crease lines crossing the grey arcs at right

STRONGEST Dry-brush streaking at the ends of the 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, 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: 3 principal ink masses traced (cyan), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 19 edge segments, 42% crisp, 58% soft or bloomed, 0% broken.

Tonal depth held at rung 1.

5 steps: not applied
RULE 2A major flaw

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

A read that breaks the reply format is discarded.

THE ARITHMETIC

V23 rating 7.2.

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.
