Scoring
How GlideComp scores competitions
Every competition is scored in one of two formats, which the organiser picks in the competition's settings. The last two guides explain what GlideComp checks and repairs in each tracklog before scoring it.
GAP race to goal
The FAI/CIVL standard, used at most hang gliding and paragliding competitions. Pilots race a set course of turnpoints to goal. A task is worth up to 1000 points, shared out for distance, time, leading and arrival according to how each pilot did against the rest of the field.

Everyone launches from the same place and flies as far as they can, with no course and no goal. Your score is the straight-line distance, in metres, from the edge of the take-off cylinder to the furthest point you reached.

GPS dropouts and signal reflections sometimes log an altitude no glider could fly. GlideComp repairs these spikes before analysis, by checking the GPS altitude against the barometer, or against what a glider can physically do when there is no barometer. The pilot's report card lists every repair. Positions, times and the original file are never changed.
Read how data cleaning worksTrack validity checks is this really your flight of this task?
Sometimes a pilot uploads the wrong file, such as a flight from another day or another site. GlideComp checks every tracklog against its task, and withholds one that cannot be that flight. Lesser concerns are only flagged and never change a score. The scorekeeper can overrule any verdict.
Read how track validity worksWhen the scoring changes
When GlideComp fixes a scoring fault or moves closer to the FAI specification, every competition is rescored, so your points can change without the organiser doing anything. Each change is written up with what moved, who it affects and why. Read the scoring changelog on GitHub.
