Quota confusion

I am setting up project quota at 95% of the storage capacity. df shows:

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/dm-0 13672271872 11816602148 1855669724 87% /mnt/storage1

so I set it:

limit -p bhard=12988658278k 1

but when I do an xfs_quota "quota -p 1":

Disk quotas for Project shares (1)
Filesystem Blocks Quota Limit Warn/Time
Mounted on
/dev/dm-0 11816148292 0 12988658280 00 [--------]
/mnt/storage1

the number of blocks is less than the limit.

Also, an xfs_quota df:

Filesystem 1K-blocks Used Available Use% Pathname
/dev/dm-0 13672271872 11816602148 1855669724 87% /mnt/storage1
/dev/dm-0 13672271872 23632296584 1855669724 173%
/mnt/storage1/share

I do not understand the lower "Used" figure.

Any help appreciated.
