The issue is partially due to the massive number of soft interrupts being generated by this job, and the frequency at which top is doing the sampling. Increasing the sampling rate should improve accuracy, but increased sampling requires stealing time from the processes themselves. Unfortunately this job type is a limitation of the accounting in the kernel, and can not be fixed without negatively affecting performance or significantly rewriting the kernel accounting subsystem in a way currently not invented.

As a result we will be closing this bug within the next 4 days if there are no objections.
