 ## Rationale
 
-An increment of 50 represents a meaningful expansion (~25%) without dramatically altering the message complexity in MonadBFT's voting rounds. Larger single-step increases carry higher risk of unforeseen performance degradation; smaller increments would add process overhead without proportionate benefit.
+An increment of 100 represents a meaningful expansion (~50%) without dramatically altering the message complexity in MonadBFT's voting rounds. Larger single-step increases carry higher risk of unforeseen performance degradation; smaller increments would add process overhead without proportionate benefit.
 
 The increase allows for greater decentralization in the active set, enforcing stronger fault tolerance and economic security.
 
 ## Backwards Compatibility
 
-This MIP does not introduce backwards incompatibilities. The change is additive: existing validators in the active set are unaffected. The hard-coded `ACTIVE_VALSET_SIZE = 200` MUST be updated to `250` to support the new parameter values prior to activation.
