Good, I wasn't sure if it's me not understanding it. :-)
Also, the line
agsize rounded to 65264, swidth = 64
should be changed to use units:
agsize rounded to 65264b, swidth = 64k
and so should all other values also I guess. It would be good at least,
as the current mixture is confusing:
imaxpct=25 = sunit=16 swidth=64 blks,
The "pct" is clear, but could have "%", swidth has the units "blks", but
what is "sunit" is only clear if you read the man page.
Yes, somewhat messy, maybe there can be a full cleanup. :-)
