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
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

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: 0.029 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 2 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 translucent arcs like R3, with fluent, legible layering, but the dark interiors measure flat, the right side is crowded, and small blots mark the left dark sector.”

Form · FLUENT

Arc bands follow the brush's radial sweep around the hub with clean dry-brush ends; the left dark sector is broad and slab-like but still follows the arc.

WEAKEST Broad left dark slab, filled more than travelled

STRONGEST Radial arc bands of top-centre fan

Tonal depth · THIN

Dark interior modulation 0.029 is flat by measure; tone mostly changes at the overlaps between passes, with some grain in the centre fan only.

WEAKEST Left dark sector interior, uniform grey-black

STRONGEST Brush-grain banding in central dark fan

Layering · ORDERED

Pale outer arcs, mid-grey sectors and dark inner sectors overlap translucently in a readable order around the whole fan.

WEAKEST Dense right overlaps, where passes are harder to separate

STRONGEST Stacked translucent arcs in the upper rim

Composition · WORKING

A radial fan around a white hub at the bottom centre gives clear movement; the ink covers 78% of the sheet, the right side crowds, and the top corners are leftover.

WEAKEST Heavy, crowded right half of the fan

STRONGEST Empty hub and radial sweep

Material and surface · FLAWED

Dark drop spots sit inside the left dark mass, visible in the colour view; there is a spatter blot at the bottom right, crease lines in the centre fan, and a drip in the hub.

WEAKEST Blot drops inside left dark sector

STRONGEST Dry-brush grain at the arc ends

FLAWS

6 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 6 distinct places, 23 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), 3 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 81% crisp, 19% soft or bloomed, 0% broken.

THE ARITHMETIC

V23 rating 7.2.

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.
