A short bit on GAP 2011
Some of you will have noticed that since summer 2011, FS comes with an additional scoring formula: GAP2011. Unfortunately, there is no documentation around that explains what changes were made from GAP2008 to GAP2011. We’re working on improving the documentation for FS, which includes a complete explanation of the current GAP implementation, but until we’re done with that, here in short, the changes implemented in 2011:
- Altitude bonus in stopped tasks: we take the position at the time the task was stopped, calculate altitude over goal, then assume a 2:1 glide (default, can be changed) to determine a bonus distance. If that one is bigger than the best distance the pilot reached previously, we use the bonus distance, otherwise the best distance as before.
- Devaluation of tasks with no pilot in goal: If no pilot reaches goal, the task is devalued by an additional factor, default (as set by the CIVL plenary in 2011) is 80%
- Devaluation of stopped tasks: Stopped tasks are devalued by an additional factor, default (as set by the CIVL plenary in 2011) is 70%. This is not combined with change 2, so even a stopped task with no pilot in goal is devalued only by factor 70%.
The 2011 CIVL plenary decided to apply those changes to all FAI Category-1 paragliding events. That usually means they’ll also be applied to most FAI-2 events, since scorers/meet directors tend to just apply the same rules there. They do not apply to Hang Gliding competitions, but of course organizers of FAI-2 events are free to use those settings as well.
I hope this helps in the short term – we’ll be coming up with a more in-depth documentation of GAP later this year.
