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
8
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

4 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: 0.041 (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

“A radial fan of arcs, like R3 but more crowded and heavier on the right. The translucent layering is strong. The dark interiors are flat, and the bulky right mass and dense coverage hold the sheet at ordinary level.”

Form · BUILT

Radial arc segments hold their walls and track the stroke, but the right-centre dark mass and small central rectangle read as filled blocks.

WEAKEST Bulky dark slab in right-centre mass

STRONGEST Arced outer ring segments following brush travel

Tonal depth · MODELLED

Grey arcs show drag banding and grain, but dark interior modulation 0.041 is flat; the right dark mass is uniform inside.

WEAKEST Flat interior of right-centre dark mass

STRONGEST Banded grey arcs in upper-left quadrant

Layering · ORDERED

Many translucent overlapping arc passes, four tonal steps; overlaps read in sequence around the radial structure, building depth.

WEAKEST Dense dark overlaps at right lose some order

STRONGEST Stacked translucent arcs along left and top

Composition · WORKING

Semicircular radial fan with central void and vertical gap gives direction, but 77% coverage crowds the sheet and right side sits heavy.

WEAKEST Crowded heavy right half against cramped centre

STRONGEST Radial fan with central white void

Material and surface · SOUND

Ink controlled with grain and dry edges; small dark spots in lower-left band; red dot and pink wash are deliberate colour ink.

WEAKEST Small spots in bottom-left dark band

STRONGEST Dry-brush grain in upper arcs

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, 8 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), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 18 edge segments, 56% crisp, 44% soft or bloomed, 0% broken.

THE ARITHMETIC

V23 rating 6.7.

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.
