Processing logic in a memory device receives a command to execute a set of read operations having read voltage levels corresponding to a programming distribution associated with the memory device. A set of memory bit counts is determined, where each memory bit count corresponds to a respective bin of a set of bins associated with the multiple read voltage levels of the set of read operations. A valley center bin having a minimum memory bit count of the set of memory bit counts is determined. The processing logic determines that the minimum memory bit count of the valley center bin satisfies a condition and an adjusted read voltage level associated with the valley center bin is identified in response to the condition being satisfied.
