The Reward Rate (displayed as fspRewardRate) represents the FTSO Scaling Provider reward rate derived from WNAT (Wrapped Native Asset Token) claims.

It reflects how effectively a data provider is earning rewards relative to the delegation it receives. A higher reward rate indicates stronger provider performance over the measured period.

Values greater than or equal to 1 are considered anomalous and are displayed as -- in the UI. Valid reward rates are shown to four decimal places.

The Reward Rate CV (coefficient of variation) measures the consistency of a provider's reward rate across epochs. A lower CV indicates more stable, predictable performance.

The Staking APR estimates the annualised return for delegators staking to a validator node. It is calculated as:

Where:

• nodeRewardAmount — the reward distributed to the node for a given reward epoch.
• normalDelegations — total delegations to the node, excluding the validator's self-bond.
• epochsPerYear — the number of reward epochs that occur in one calendar year.

The per-epoch rate is extrapolated to an annual figure. Actual returns may vary as reward amounts and delegation totals change each epoch.

The FSP APR (FTSO Scaling Provider APR) represents the estimated annualised return for delegators based on FTSO reward distributions.

To filter out unreliable outliers, FSP APR values exceeding 15% are hidden from the UI and displayed as --.
