# T_320

[The work as shown](https://peteryuill.art/works/T_320). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.05.31, day 154
- **Size:** 97 × 180 cm
- **Paper:** S11, Red Star Mo She Special Effect Xieyi, raw
- **Inks:** MB4, MB5, MB6
- **Phase:** P3 The Floor Rises

- **Shown on the site:** yes (V23 rating of 5.0 or higher)

- **Early storage triage:** SA: save, archive (Peter's early system, since retired)

## Measured · V23 (v23.8)

- **V23 rating:** 6.5
- **Form:** 2
- **Tonal depth:** 2.2
- **Layering:** 2.2
- **Composition:** 2.4
- **Material and surface:** 2
- **Ink cover:** 60%
- **Dark share:** 33%
- **Tonal steps:** 5

- **Flaws named by the reads:** water stain 2, other 7, tide line 2

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](https://peteryuill.art/method).

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.

![T_320, tone-stretched]

![T_320, classed by brightness]

60% of the sheet carries ink

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: 0.054 (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 spiralling composition of nested arcs with a strong sweep and a well-shaped open centre. The grey masses are fairly flat inside, the central wedge is blunt, and the splatter at right is loose. Better than R2 on composition.”

Form · BUILT

Inner dark arc and upper dark band follow the brush's travel; the central grey wedge is a bulky slab with a squared lower end; the right splatter is loose.

WEAKEST Central grey wedge ends in a blunt, filled-in edge

STRONGEST Inner dark arc, left, with dry-brush tail

Tonal depth · MODELLED

Dark arcs show streaking and banding (modulation 0.054); the outer grey band and the central wedge are mostly even mid-grey with little internal grading.

WEAKEST Upper-left grey band, flat and even inside

STRONGEST Upper dark band with streaks and stepped density

Layering · LEGIBLE

Grey wash passes lie under the dark arcs and stay readable; the dark band over the grey wedge is clear; roughly three passes, not a sustained sequence.

WEAKEST Right splatter zone blurs the order of passes

STRONGEST Dark arc laid legibly over the grey band, left

Composition · COMMANDING

Nested arcs carry the eye from lower left, up over the top and out into the splash at right; the open centre paper is strongly shaped.

WEAKEST Busy drip and splatter cluster at right

STRONGEST Spiralling sweep of arcs around the open centre

Material and surface · SOUND

Ink is mostly controlled with good dry-brush edges; the central grey wedge has a slightly milky mottle; stray drops at top right and drips at lower right.

WEAKEST Mottled, cloudy interior of central grey wedge

STRONGEST Dry-brush tail on the inner arc

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, 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: 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 19 edge segments, 32% crisp, 32% soft or bloomed, 37% broken.

RULE 1 Two tonal steps or fewer

Tonal depth held at rung 1. 5 steps: not applied

RULE 2 A major flaw

Material held at rung 1. Mild waves in the unmounted paper are never a flaw. none named

RULE 3 Any quality below 0.5

The rating cannot exceed 4. lowest 2.0

RULE 4 At least two valid reads

A read that breaks the reply format is discarded. 5 of 5 valid

THE ARITHMETIC

## V23 rating 6.5.

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.

MEAN RUNG 2.16 (2.0 + 2.2 + 2.2 + 2.4 + 2.0) ÷ 5

RAW 5.32 1 + 2 × 2.16

RATING 6.5 5 + 2.086 × (5.32 − 4.60)
