For the second installment of TD101, let’s get into the question of TGP and tiebreakers.
TGP (Tournament Grading Percentage) is the metric we use to determine how many meaningful games were played in a given tournament. When the IFPA initially came up with TGP as a metric, we made the decision that 25 is a reasonable number of meaningful games to be played in a tournament to determine a winner. Anything below that 25-game threshold and we remove some points from the event.
A meaningful game of pinball is one in which at least 3 balls are played in their entirety. Any game in which fewer than 3 balls are played is counted as less than a full meaningful game. If 1 ball is played, the game counts as 1/3 of a meaningful game. If 2 balls are played, 2/3.
In terms of tiebreakers, does a tie breaking game ever count toward the TGP? The answer is no.
Tiebreakers never count toward the TGP because they don’t count as additional games played in the tournament. Instead, the resolution of a tie is considered a clarification of the results. So if you have tiebreakers in your event, those only affect the standings (like whether a player comes 3rd or 4th) and do not contribute to the TGP.
Hope this helps, and thanks for reading!
