Noticed on ADS 14-beta-55.

When importing attached zips.csv file into an empty collection on mongodb using 'Tools->Import Data' of ADS, the status of the import is shown as 'Inserting <number> of ~39,125'  (Pls refer to attached screenshot import_status.png) when the insertion is in progress.

After the insertion is completed, the status is displayed as 'Completed:Inserted 29,467 row(s)'  (Pls refer import_final.png)

There seems wide margin discrepancy between estimated row count(~39,125) vs actual row count(29,467). Could it be made more realistic? Thanks
