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
5.5
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

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: 0.057 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 1 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 strong vortex sheet. The banded right arc has real tonal and layered depth, and the empty centre is shaped. The lower-left blots are less refined, and there are minor drip rings near the right mass.”

Form · BUILT

Right arc bands follow the stroke cleanly; the left sweeping curves hold, but the lower-left blobs and clotted strokes are bulky and less exact.

WEAKEST Lower-left cluster of blotted ovals and spatter

STRONGEST Right concentric dark arc following brush travel

Tonal depth · DEEP

The right dark mass shows arcs, grain and stepped bands. The left grey sweeps are graded inside. Modulation 0.057, with three tonal plateaus from black to paper.

WEAKEST Darkest band of right arc somewhat even

STRONGEST Right arc's banded concentric greys

Layering · ORDERED

Several translucent grey passes stack under the black in both the right arc and the left sweep. You can read their order, and the overlaps build depth.

WEAKEST Lower-left overlaps slightly clotted

STRONGEST Translucent stacked bands of right arc

Composition · COMMANDING

Two curving masses form a vortex around a shaped empty centre. The bottom connecting stroke carries the eye across, though the lower left is busy.

WEAKEST Crowded lower-left spatter zone

STRONGEST Shaped empty centre between two opposing arcs

Material and surface · SOUND

The ink is controlled and the colour spatter and blue dots are deliberate. Small ring-like drops and blots sit at the lower right of the big arc; they are minor.

WEAKEST Small ring drops beside right arc

STRONGEST Dry-brush grain along the right arc's edges

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, 10 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: 1 principal ink mass traced (cyan), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 17 edge segments, 41% crisp, 41% soft or bloomed, 18% broken.

THE ARITHMETIC

V23 rating 7.8.

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.
