How does BGA determine "50%" of a game?

There are games that are clearly going poorly but BGA won't allow conceding until 50% is finished. How does BGA calculate what is 50% of a game like Dungeon Twister? Can't be # of turns, since games can be over quickly or go very long. And why is there even a 50% requirement to concede? Seems like a waste of everyone's time.

50% is number of progress of each game.

In Dungeon Twister it's depending how many squares you're from the goal... it only count the first five chars.

BGA add 50% minimal for concede because some people just started a game and concede faster, also... for some players is a little impolite concede a game.
