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.

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: 0.042 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“This radial sheet is like R3 but busier: the overlapping passes and red bands are layered so each can still be read. The dark hub is flat inside, the right-side blocks look stiff, and the lower centre is crowded.”

Form · BUILT

Left arcs and ring segments follow the brush's travel; right-side fan becomes boxy slabs, e.g. the dark block at right edge and stacked rectangles.

WEAKEST Stiff rectangular blocks at right edge and centre-right

STRONGEST Concentric arc segments around the central hub

Tonal depth · MODELLED

Measured dark modulation 0.042 is flat; central black disc and lower-centre darks are uniform, though grey arcs and fan wedges show grain and stepped density.

WEAKEST Central dark hub mass reads flat

STRONGEST Grained grey arc upper-left of hub

Layering · ORDERED

Many translucent grey passes overlap legibly across the fan; red bands sit as a clear separate pass under and beside black; order readable across most of sheet.

WEAKEST Lower-centre overlaps compress into dense dark

STRONGEST Translucent fan wedges stacking toward top right

Composition · WORKING

Hub left-of-centre drives a diagonal fan to the upper right, shaping the empty top; lower half jammed and heavy, right-edge block feels cut off.

WEAKEST Crowded dark lower-centre and cropped right block

STRONGEST Radial sweep from hub up to top right

Material and surface · SOUND

Ink controlled; dry-brush grain used in arcs; only paper creases and faint lines in empty paper; no stains in principal masses.

WEAKEST Dense lower darks lose material character

STRONGEST Dry-brush grain in upper-left grey arc

FLAWS

7 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 7 distinct places, 11 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), 5 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 20 edge segments, 35% crisp, 50% soft or bloomed, 15% 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.
