Tick
The relief letter is a caption. The tick is the survey.
We put a gauge on the heel and a number on the lot sheet. If they disagree, the sheet wins. Rogue dust is hard on stickers anyway.
Benno walks the chain from the highest scoring head down. Collisions get a rust tick. Empty terraces get a question, not an automatic grind. A question that stays unanswered does not become a sale.
