How long a USDC leadership call actually holds, from hourly on-chain attestations (EAS): median lead duration, survival at 6/24/72h, how much of the rotation is the same two protocols trading places, and what chasing the leader is worth per $10k before gas.

Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
