# PrimalScore
> The 0 to 100 grade on every Alpha row: evidence strength times on-chain legitimacy.
Every row on the Alpha page carries a PrimalScore in the **Score** column: a number from 0 to
100 with a grade under it.
## What it measures
Two reads, multiplied:
* **Strength.** How much the live market evidence agrees: the breadth, quality, and persistence
of the activity behind the move.
* **Legitimacy.** What the chain says about the token itself: holder concentration, sniper and
insider cohorts, dev behavior, liquidity state, security checks.
Multiplied means one rotten side sinks the whole number. A loud token with an ugly holder book
cannot score its way up on volume, and a clean token with no real activity does not score on
cleanliness alone.
## The grades
| Score | Grade | Read |
| --------- | ---------- | -------------------------------------------------- |
| 72 to 100 | **PRIMAL** | Exceptional evidence and clean structure. Rare |
| 60 to 71 | **STRONG** | Solid evidence, structure holds up |
| 36 to 59 | **FAIR** | Mixed. Read the cohorts and the flow before acting |
| 0 to 35 | **WEAK** | Thin evidence or structurally ugly. Usually both |
Look at the three rows above: the 77 PRIMAL sits on an established token with deep activity, and
the 51 FAIR is 57 minutes old with early evidence still forming. Score tracks the quality of the
case, not the age or the market cap.
## Frozen at signal time
The score you see is the score the call fired with. It never repaints. When you scroll Prime
weeks later, the number a call is judged by is exactly the number subscribers saw at entry.
PrimalScore ranks the quality of the evidence. It does not predict profit. A 77 can bleed and a
40 can run. The score tells you the case is real; the trade is still yours.
