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
9
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

6 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 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

“Radial layered fans in the manner of R3, with legible translucent passes. The bulky, nearly flat dark mass at the bottom right crowds the composition and keeps form and tone at an ordinary level.”

Form · BUILT

Upper fan arcs and the lower centre arc follow the brush's travel; the right-hand dark block is massed and stepped, with a filled-in bulk.

WEAKEST Bulky stepped dark mass filling the bottom right

STRONGEST Dry-brush arc stroke at lower centre

Tonal depth · MODELLED

Upper fans show grain, concentric arcs and stepped greys; the large right dark mass is only lightly modulated (0.057) and reads nearly flat in colour.

WEAKEST Interior of the right-hand dark mass, mostly uniform

STRONGEST Grey arcs with banding around the upper-left hub

Layering · ORDERED

Several translucent passes are stacked in a clear radial order in both fans, with legible stepped edges; six tonal plateaus.

WEAKEST Right dark mass covers earlier passes beneath it

STRONGEST Translucent stepped bands of the upper-left fan

Composition · WORKING

Two radiating fans set up a diagonal movement and the empty lower left is shaped; the bottom-right corner is jammed and heavy.

WEAKEST Bottom right crowded by the heavy dark mass

STRONGEST Diagonal pull between the two radial fans

Material and surface · SOUND

Ink is controlled and the dry-brush edges are used; only minor spatter and faint brownish spots sit on open paper, away from the principal masses.

WEAKEST Small speckles and faint marks on the lower-left paper

STRONGEST Dry-brush grain in the lower centre arc

FLAWS

2 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 2 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: 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 19 edge segments, 47% crisp, 42% soft or bloomed, 11% broken.

THE ARITHMETIC

V23 rating 7.5.

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.
