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
7
Peter's rating is his own eye, not the engine's, and he never gives a 10.

Older engine

V10C
7
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: 0.054 (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

“A concentric arc sheet in R3's family, with fluent arcs and ordered translucent layering. The black arc is fairly flat inside and the composition is less resolved than R3's. The surface is sound, with only minor crease marks.”

Form · FLUENT

Concentric arc bands follow the brush's curved travel; walls hold cleanly. Squared stepped terminations at the upper-left greys are slightly blunt, but not clumsy.

WEAKEST Stepped blocky ends of upper-left grey bands

STRONGEST Broad black arc sweeping centre to bottom right

Tonal depth · MODELLED

Seven tonal steps across many grey bands. Interior modulation of 0.054 is only modest, and the large black arc and the black block at left read mostly flat inside.

WEAKEST Main black arc interior nearly uniform

STRONGEST Dry-brush inner grey arc, bottom centre

Layering · ORDERED

Several translucent grey passes overlap in a readable order, building out from black to pale outer arcs at right and left. The overlaps stay legible.

WEAKEST Black arc covers rather than shows underlying passes

STRONGEST Stacked translucent grey arcs, upper right

Composition · WORKING

The concentric sweep gives clear direction and the white core is shaped. The left fragment and the top-left paper wedge feel less resolved than R3's balanced opening.

WEAKEST Left arc fragment feels cut off and wedged

STRONGEST Large arc sweep around the white centre

Material and surface · SOUND

Ink is controlled with no tide lines or rings. Crease networks show in the greys at right and centre, and there is a small speck at the left edge.

WEAKEST Paper crease lines visible through grey bands

STRONGEST Grainy dry-brush texture in inner arc

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, 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: 5 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 23 edge segments, 39% crisp, 52% soft or bloomed, 9% broken.

THE ARITHMETIC

V23 rating 8.2.

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.
