Introducing the Threshold
The threshold is an advanced feature on Toornament meant to alter a bracket structure in order to qualify more than one participant. It can be found under the "Advanced" tab of any Bracket-type Stage Configuration.
By default, the threshold of a stage is 1, meaning a single participant comes out on top of it. If you increase this value to N, you will effectively remove the matches used to decide between the N best participants.
This feature is mostly used in the GSL-like Bracket Groups:
In this structure, each group is a standard Double-Elimination bracket, where the Grand Final is not played, because we want to qualify 2 participants per group. Hence, this particular stage has the following settings:
- Type: Bracket Groups
- Bracket Type: Double Elimination
- Size: 32
- Groups: 8
- Threshold: 2 (the value is for each group, not the whole stage)
A threshold can only be one of a set of values, depending on the type of bracket you wish to use it:
- Single-Elimination Bracket: 1, 2, 4, 8, 16, 32 etc.
- Double-Elimination Bracket: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32 etc.
This comes from the fact that you can only set a threshold that would remove all matches from an entire round, hence an number of participants different depending on whether you have a loser bracket or not.
