where XXXXX is replaced by the month/year (i.e. sep01 or july02, etc).

I can't vouch for the numbers as I am prone to typos. Please double check them yourselves.
The good news is that with heroic effort the INS can dole out ~120K approvals in a single month (nov01). And the bad news is that they can have a negative approvals total (sep02). I am just guessing that this is due to a problem discovered by audit, etc.
It will be interesting to see the numbers for the coming few months.
