Using this search prompt code, we can see that multiple setter functions exist in scope, with them not having any check that the new accepted value is not equal to the previously stored value.
For example, setReward() checks that the new value is <= whereas it should only check < leading to an unnecessary update of totalRewardX64 if _totalRewardX64 is already == totalRewardX64.
Another example would be the below, that does not implement any checks whatsoever:
Unnecessary code execution.
Introduce equality checkers for setter functions.
