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
4.5
Peter's rating is his own eye, not the engine's, and he never gives a 10.

From an earlier engine (V7). 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

5 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: 0.049 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“An ordinary sheet. The layered diagonal bands give it movement and some legible overlaps, but the bulky, cloudy dark mass in the lower right is weighed down by blooms and fused passes, which pulls the sheet toward R1.”

Form · BUILT

Diagonal bands from centre-left to lower-centre read as travelled strokes; the right dark slab and lower-left mass are bulky and partly blob-like.

WEAKEST Bulky dark slab at right, stiff rectangle

STRONGEST Diagonal arcing bands crossing the centre

Tonal depth · MODELLED

Centre bands show stepped density and grain; right block has streaks; lower-right mass is murky. Modulation 0.049 just above the flat threshold.

WEAKEST Lower-right dark mass, cloudy and fairly uniform

STRONGEST Overlapping translucent bands in centre

Layering · LEGIBLE

Grey slabs underlie darker diagonals with legible overlaps in centre; at lower right the passes fuse into one dark mass and order is lost.

WEAKEST Lower-right where passes merge into dark

STRONGEST Stacked translucent bands at centre

Composition · WORKING

Diagonal movement rises to the right block; top paper is shaped by the top-left band. Lower half is jammed with dark, bottom-right dead and heavy.

WEAKEST Heavy lower-right quadrant crowds the frame

STRONGEST Upward diagonal thrust from lower-left to right block

Material and surface · FLAWED

Lower-right and lower-centre masses carry mottled cloudy patches and bleed marks visible in colour view; pale blotch inside lower-left mass; fold creases.

WEAKEST Cloudy blotched wash in lower-right dark mass

STRONGEST Dry-brush feathered edge at right of block

FLAWS

7 distinct places, 1 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 7 distinct places, 17 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. A major flaw holds Material and surface at rung 1.

GEOMETRY

Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 2 principal ink masses traced (cyan), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 20 edge segments, 55% crisp, 35% soft or bloomed, 10% broken.

RULE 1Two tonal steps or fewer

Tonal depth held at rung 1.

5 steps: not applied
RULE 2A major flaw

Material held at rung 1. Mild waves in the unmounted paper are never a flaw.

RULE 4At least two valid reads

A read that breaks the reply format is discarded.

THE ARITHMETIC

V23 rating 5.0.

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.
