Jersey rarity.

Capacity, first-registration year and cycle filters select models with matching registrations; unknown/withheld values are excluded by ranges. Count bands use the whole snapshot, not the filtered count. Published ratings and competition ranks stay fixed when filtering. Only publication-eligible exact model identities receive rarity; source-label groups are excluded from these rankings, but all registrations remain in the original category denominators. “Other” retains eight separate rarity populations.

The diamond badge shows a 1–100 Jersey rarity rating: 1 + 99 × the published V7 percentile (0–1). This is a display scale; published percentiles, competition ranks and counts remain unchanged.
