```csharp
public double AllowedEntropyDeviation
```

Represents the allowed entropy deviation between the cluster's current entropy, against the theoretical maximum. Values lower than this are practically considered as "maximum", and the current rebalancing session will stop. This acts as a base rate if [ActivationRebalancerOptions](/orleans/docs/api/csharp/microsoft.orleans.runtime/orleans.configuration.activationrebalanceroptions/) is set to `true`.
