Question is : Do you scan the uscis database using a program while incrementing receipt numbers to a) determine the current status b) to discover new cases (and their types)?

No. I only query OUR datastores for approvals or changes which are fed by data contributors.

>>If you you answered NO, the question is how you get the receipt numbers?
It's data contributors's job.

As I mentioned before, we are working hard on a way by which everybody are their own data contributor if they are want to.

>>what do you mean by "High standard of cross-examination" ?
Verified by at least 2 or more independent data contributors.
