For Classic atomic round 1343, the before-cost break-even line is MMC60 = −CORR60 / 5. That follows from the configured weighted score, 3 × CORR60 + 15 × MMC60, crossing zero. It does not say that staking earns an attractive return on all committed capital.
Revised September 8, 2026. Earlier break-even rates based on 0.5 × CORJ60 + 2 × MMC and a universal 25% clip are withdrawn.
Separate score break-even from economic viability
Suppose CORR60 is +0.02 and MMC60 is −0.003. The weighted score is +0.015, giving a 1.5% net return on that position before costs. If 1 NMR was assigned to it, the outcome is +0.015 NMR. It is not 1.5% earned on every token tied up elsewhere.
The cost question also needs funding dates, idle capital, fees, infrastructure expense and the participant’s chosen USD valuation. No score threshold can answer all those questions without a specified denominator and horizon. The round-return guide explains why multiplying by daily cadence fails.
Verify the applicable policy first
Round 1342 used a different Classic configuration: CORR20 × 0.75 and MMC × 2.25, with a 0.05 legacy clip. Signals and Crypto have their own policies. The active score names, multiplier and cap belong to the round record, as displayed in Rounds.
I would use the zero-score line to diagnose a model’s payout components. I would require a dated position-and-funding ledger before calling that model economically viable for an account.
