.zip up the logs you would like to import all at once. You can only do one week at a time. No need to rename the files to anything in particular. Make sure the correct year and week are selected and hit the Touch Me button. Even with 16 games, it's fairly fast.
Uploading a gamelog will:
1. Import all the game stats for that game
2. Update the schedules table with the results
3. Update the standings table with the results
