Series drift is usually blamed on the model. The desk blames the paperwork. A character described from memory is re-cast at every sitting, because memory edits as it goes: “glossy chestnut hair” in one brief becomes “dark flowing hair” in the next, and the audience watches a stranger climb the chart in the original performer’s place. The repair is clerical. Write her down once, on a card you paste rather than retype, and let the card do the remembering.
Five fields, in order
A working chart card holds five things. Age — a number, always 25 or over. Hair — colour, length, one usual style. Build — two or three words, no more. Face — one or two details that endure. Mark — the scar, the mole, the ring that survives a crop and settles recognition at a glance. Everything else belongs to the scene line: outfit, room, light, pose. Scene lines are supposed to change. Fields are not.
Two habits keep a card honest. Fields are stated plainly and positively — “glossy chestnut hair in a side-swept finger-wave bob” survives generation, while “beautiful hair” is a verdict, and verdicts get re-argued at every attempt. And the card is versioned. When the performer is deliberately changed — a new cut, a new mark — the new text is saved as version two with a date, so an earlier set can still be remade exactly as it charted the first time.
Producing against the card
Production then becomes a quiet routine. Pair the card with scene lines that share one room and one light, and make the sitting at the standard model’s 6-credit price. Chart the results without mercy and keep the strongest third. Spend on repairs, swaps and upscales only after the cull. When a frame returns off character, the cause is almost always visible on paper: a scene line contradicted a field, or a field was too vague to hold its place. Both are fixed on the card, not in the settings.
What a card cannot do
It cannot chart a woman who was never decided. If the fields are adjectives — lovely, striking, flawless — no card and no model will keep her in place. Decide her on paper first. The card is not where the imagination happens; it is where the imagination is filed, so the desk can find it again.
