 The configurable values are as follows:
 
-* `TimeoutPropose` 
+* `TimeoutPropose`
 	* How long the consensus algorithm waits for a proposal block before issuing a prevote.
 	* If no prevote arrives by `TimeoutPropose`, then the consensus algorithm will issue a nil prevote.
-* `TimeoutProposeDelta` 
+* `TimeoutProposeDelta`
 	* How much the `TimeoutPropose` grows each round.
-* `TimeoutPrevote` 
-	* How long the consensus algorithm waits after receiving +2/3 prevotes before 
-	issuing a precommit.
-* `TimeoutPrevoteDelta`
