uint32 public constant RATE_CONFIDENCE_INTERVAL = 30 days;

RATE_MULTIPLIER

The percent (in basis points) of the earner rate that will be effectively used.

uint32 public constant RATE_MULTIPLIER = 9_000;

ONE

100% in basis points.

uint32 public constant ONE = 10_000;

_MAX_EARNER_RATE

bytes32 internal constant _MAX_EARNER_RATE = "max_earner_rate";

_EXP_SCALED_ONE

The scaling of rates in for exponent math.

uint256 internal constant _EXP_SCALED_ONE = 1e12;

_WAD_TO_EXP_SCALER
