The Annual Percentage Yield (APY) from a delegator's perspective in the given period.

The given period is defined by all requested spendable epochs: all requested epochs except the current and previous.

Formula: (memberRewards / (activeStake - pledge)) / days_per_epoch * 365

Where: memberRewards, activeStake and pledge are the sum of the respective data from all epochs in the given period.

Use ros instead

blocksCreated: number

Total blocks created by the pool.

delegators: number

Number of stakeholders, represented by a stake key, delegating to this pool.

lastRos: Percent

The annualized Return Of Stake for the last LAST_ROS_EPOCHS epochs from member perspective.

livePledge: bigint

This can be used to determine the likelihood of the pool meeting its pledge at the next snapshot.

ros: Percent

The annualized Return Of Stake for the life time of the pool from member perspective.

The period of ROS computation depends on requested QueryStakePoolsArgs.epochsLength: if provided, ROS is computed on the last requested epochs, otherwise for the life time of the pool.

The current saturation of the pool. The amount of rewards generated by the pool gets capped at a pool saturation of 100%; This is part of the protocol to promote decentralization of the stake.
