1. A memory sub-system comprising:
a memory device comprising a set of blocks; and
a processing device, operatively coupled with the memory device, to perform operations comprising:
detecting a block storing corrupt data;
based on detecting the block storing corrupt data, determining whether to perform one or more heroic data recovery processes on the block based on a statistical correlation between reference VT distribution data and VT distribution data corresponding to the block, the VT distribution data comprising one or more VT distribution measurements corresponding to the block, the one or more VT distribution measurements including a measured VT of a memory cell in the block, data stored by the memory cell being based on the measured VT of the memory cell, the reference VT distribution data comprising one or more reference VT distributions.
