The utilization corrected write-back ratio is an estimation of what the write-back ratio would be if the application was changed so that 100% write-back utilization was achieved.
The utilization corrected write-back ratio can be displayed for the entire application, a loop or an instruction group. When it is displayed for a loop or an instruction group it is the utilization corrected write-back ratio of that specific part of the code if that specific part of the code was fixed.
