You will be able to upload one file at a time (which is when the stat extractor shows that games stats) or upload an entire folder (it will auto import all the games but no stats will show up on the stat extractor window, it will tell you that all the files you have choosen have been imported...i want to have it eventually create webpages with individual game box scores)
and as the playoff tree is now... while the season is going on it will auto update according to the standings (with tiebreakers) so it will always be "If the Playoffs Started Today". When the season is over (however long it is set for), you will no longer be able to enter regular season games into the stat extractor, only games between playoff matchups.
