    We just released FS 2020 R1.1, which includes the following changes:

    ·         Additional scoring formula: GAP 2020
    ·         Optional separate category scoring
    ·         FSDB files now include all results
    ·         A number of smaller improvements and bug fixes

    http://fs.fai.org/trac/wiki/SeparateCategoryScoring

     In most competitions, besides the overall scoring, we also produce various category scorings: Female, Sports Class, or all pilots of one nations for their national championship.

    Traditionally, those category rankings are produced by "filtering": The pilots who fall into the cateogry in question are filtered out from the overall scoring. Their score is always identical with their score in the overall ranking.

    The problems with filtering

    This filtering method is very easy, but it can lead to very tight rankings, where pilots are separated by only a very small number of points. Which potentially leads to a chance competition winner, especially in slower categories in competitions with a good number of fast wings and pilots: The slower pilots - competing in Sports Class, for example - will be bunched up towards the bottom of the ranking, with very few points to separate them. The pilots who do well within their categoriy and beat their opponents into goal are rewarded much less than the overall task winners. This because time points distribution becomes "flatter" towards the end of the race, when the slower pilots arrive in goal. For them, their differences in time translates into very small differences in time points. After a certain time, which depends on the overall winner's time, they may not even get any time points any more, which leaves them all with the same amount of distance points, and the few leading points they may get.

    Another issue is that if a task is set too ambitiously for Sports Class, but the higher-end wings do just fine, the day still counts fully for everybody, even if all the Sports Class pilots landed shortly after the start.
