Several pmatop reporting/output oddities

Screenshot showing negative per-process cpu and invalid cpu% values
Description of problem:
I've noticed pmatop in current PCP is reporting strangely in a couple of ways:
- incorrectly sorting top cpu burners. this might be a 64bit metric issue, where the metric is being displayed using 32bits worth? (attached pcp archive shows this)
- some columns are displayed with negative values (attached screenshot shows this)
- some columns are displayed with both scientific notation and with K suffix (see screenshot attached)
- column widths for some columns overflows the allotted screen real-estate (attached archive shows the problem)
Version-Release number of selected component (if applicable):
pcp dev branch exhibits the problem.
Every time for me, not so much for scox & fche after chatting. May be related to long running cpu-burning processes I have locally. An archive is attached showing the incorrect sorting.
Steps to Reproduce:
1. Run pmatop -h local:
2. Run pmatop -r atop 1
3. Both the above show the issues for me
pmatop displays either the wrong top-cpu-burners (case 2), or sometimes non-existent processes (seen in case 1 occassionally).
pmatop displays top cpu burners that match up with what top(1) shows.

PCP archive showing issues in pmatop output
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Oops, reassign back - pkgdb UI interpretation failure on my part. ;)
This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle.
Changing version to '20'.
More information and reason for this action is here:
I think the change "pmatop: use utime/stime instead of schedstat" will fix this. utime/stime units are smaller, milliseconds, and a "try_magnitude" display feature was added to try and use larger display units if possible
