Reward processing is optimal if all rewards up to the lastProcessedEpoch - 1 are available, as rewards are calculated after an epoch ends. The processing status is degraded if the following is true:
chainEpoch - lastProcessedEpoch > 1
The chain epoch is calculated by taking the epoch id from latest block, and then using that for a validators call which contains an epoch height field. In Near, this equates to 2 epochs behind hence why rewards are 3 behind.
Note:
Near rewards are 3 epochs behind real time.
