Straight from the NRMP website:
Why does it take three weeks from rank order list deadline to Match Day?
During that time, NRMP takes a number of major steps to assure the accuracy of both the Match and the subsequent release of Match information. Those steps include:
Checking the integrity and completeness of the data.
Transferring the data to the algorithm module, checking it again, and running the Match.
Verifying the results of the Match and transferring the data into the NRMP databases.
Creating more than 60,000 individual reports for applicants, programs, and schools, and assuring confidentiality of the information. The reports are then posted to the Web in accordance with the Match Results schedule.
In addition, time is allotted for unmatched applicants and unfilled programs to make decisions before Match Day.
Hope this provides some small measure of help,
The corpulent one,
Fatman
