How often will the actual tournament results be updated? (i.e. When I click on the downloads results button sometimes the latest results do not show up)

The men's NCAA and NIT brackets will be updated within 10 minutes of each game's ending. The women's NCAA bracket will be updated 1-3 times each day, depending on the round. If they are not updated as fast as you'd like you can always make a couple clicks on 'The Results' bracket to update them manually.
