With very little research done on my end, I would assume a simple
cronjob running quotacheck, maybe once an hour, should suffice.
Not sure why they don't match. Perhaps quotacheck ran earlier in the
day when the quota was higher and only updates once a day...? Not sure,
as I am a novice with quota's.
