As I said, that's an incomplete proposal only, to be expanded. I've run out of stamina a bit.

Code:

/Eigenvalues -- /       {gsub (/\.[0-9][0-9][0-9][0-9][0-9]/,"& ")}

"? It's genius!

This one is looking for n (literal dot and five digits), and adds a space (FS) after each. If $0 is modified, it's evaluated again so new fields $4 and $5 are created, which then are printed. Should $4 and $5 already exists because integer parts are smaller and space padded, it doesn't hurt as (and if) many awk use multiple FS as one per default.

To eliminate those duplicates would lead us away from immediate printing to parsing and storing the desired values and then print them in the end section. That would be the major part of implementing of what I mentioned, the template form file to be filled in with actual data. May take a while - no promises.

SYSSTAT(5)							Linux User's Manual							SYSSTAT(5)

NAME

       sysstat - sysstat configuration file.

DESCRIPTION

       This  file is read by sa1(8) and sa2(8) shell scripts from the sysstat's set of tools.  It consists of a sequence of shell variable assign-
       ments used to configure sysstat logging.  The variables and their meanings are:

       HISTORY
	      The number of days during which a daily data file or a report should be kept. Data files or reports older than this number  of  days
	      will be removed by the sa2(8) shell script.

       COMPRESSAFTER
	      Number of days after which daily data files are to be compressed, either by gzip or bzip2.

       SADC_OPTIONS
	      Options  that  should be passed to sadc(8).  With these options (see sadc(8) manual page), you can select some additional data which
	      are going to be saved in daily data files.  These options are used only when a new data file is created. They will be  ignored  with
	      an already existing one.

FILES

       /etc/sysconfig/sysstat
