How the score works
Every set gets one number from 1 to 10: how much its cards are moving together. Here is how that number is built, and what it does not mean.
What the score is
One number from 1 to 10: how much the cards in a set are moving together. A 1 means almost no shared movement, each card on its own. A 10 means nearly the whole set moving as one. Most sets sit around 5.

A 1999 card and a 2024 card are not the same thing, so they are never averaged together. Cards are measured inside their own group.
Same card over time
same card, seen twice
The cleanest reading comes from watching the same card sell again and again, not from comparing one card to a different one.
Two marks beside the score
The change. A small arrow for whether the set is more or less together than yesterday.
The background. A dot for what is underneath: cards on their own, a normal pace, or many reacting to the same signal at once.
Thin data, and quiet
When a group has only a little data, its reading is shown softer. When it has none, it shows nothing rather than guessing. A fresh set shows as warming up for a few days.
What this is not
A reading of how a set is moving. Not advice, not a price target, not a tip to buy or sell. A high score can mean cards are falling together just as easily as rising together. Past movement does not tell you what comes next.
