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.

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: 0.045 (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

“This is a concentric-arc sheet in the R3 family. The translucent layering is clear and well ordered. It is held back by flat black inner bands, blocky segment ends and a crowded, nearly full sheet with little shaped empty paper.”

Form · BUILT

Concentric arc bands hold their walls and follow the sweep; several inner dark segments end in stiff squared blocks, notably the right-centre rectangle and the lower-right wedge.

WEAKEST Blocky rectangular dark segment, right centre

STRONGEST Large dark upper-left arc following brush travel

Tonal depth · MODELLED

Grey bands carry streaked grain and stepped density, but the darkest arc segments are flat inside; dark modulation 0.0445 sits just under the flat threshold.

WEAKEST Flat black inner arcs, upper left and right

STRONGEST Dry-brush grained grey bands near centre gap

Layering · ORDERED

Several translucent passes overlap in a readable order, grey under dark, each band's edge still visible through the next, building depth across both halves.

WEAKEST Dense overlaps at lower-left dark cluster

STRONGEST Translucent stacked arcs, left half

Composition · WORKING

Arch of arcs around a central white void and vertical channel gives a clear direction; 85% coverage leaves the sheet crowded, with paper reduced to corners.

WEAKEST Crowded lower-left; little shaped empty paper

STRONGEST Central white channel splitting the arch

Material and surface · SOUND

Ink controlled and bound; small pale streaks in the lower-right dark block, droplet dots right of centre and crease lines are small, not disruptive.

WEAKEST Pale scratch streaks in lower-right dark band

STRONGEST Dry-brush edges on central grey bands

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, 15 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), 2 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 18 edge segments, 44% crisp, 50% soft or bloomed, 6% broken.

THE ARITHMETIC

V23 rating 7.3.

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.
