Each % = (exit price − entry price) / entry price. Entry is the live DexScreener price snapshot at round-start; exit is the cached price at round-end.
Hover any pick to see entry → exit prices. Tap 📈 to open the live DexScreener chart for that token and verify the math yourself.
A pick marked ~ no baseline means the token wasn't in the price cache at round-start, so no real entry was snapped — the scoring engine fell back to a synthetic placeholder. We hide the % rather than show a hallucinated number. New rounds (after the round-creation upgrade) won't have this — every arena token gets a real entry.
Settlement is on-chain for sponsored pools — the 60/30/10 split paid out is visible in the treasury wallet's tx history.
