My daily reports regularly contain lines like
the following (commas added):

NOTES:

The first 3 are Windows partitions and are using ZWC
on the clients. They always show up "big". Others
show up sporadically, but I can assure you my laptop
"vost" does not have a 17 terrabyte drive

Obviously these are KB, not MB as the units suffix
suggests. But even adjusting for that, the estimates
are way off. For example, 6.9GB reported in the above
compared with 1.4GB dumped in the Summary below.

Jon,

We also see 'big estimate' output for some partitions.

I assumed some sort of bounding but never looked into
it any further.

Reminds me of the O (big-oh) and omega we'd compute for
algorithms back in computer science class [upper and lower
bounds limits for algorithms]. Something that I suspect is
missing from more current programming classes.
