The diskquota utility gets its information from the Quota.Sys file
on each disk. That file is updated periodically by the file system.
Reason number 1 why the dir/size/grand didn't match up to what
the Diskquota utility reported.

Reason number 2, is that the dir/size/grand reports only the *actual* 
which amount of data in the file. The file may actually have allocated
more space than it is currently using. You may look at how much space it
has allocated with a Dir/size=All. Even then, I'm not entirely sure whether
or not that the size of the file headers are taken into account..
