Little difference between Airscore & FS

[yanglingfei0912]

The same comp, same tracklog, it happens a little difference between Airscore & FS with result, by PWC2019. who know the reason? 14423678@qq.com

It is difficult to know without seeing the example (are you able to share the URL etc?) but as a generalisation:

Whilst the rules are defined by GAP and PWC the way to calculate some of the fundamentals are not defined and standardised. For example:

 There are different ways to calculate the distance between 2 points (say a pilot's GPS lat/lon and the goal line).
There are different ways to calculate the shortest path from a geographic point (lat and long) to the goal via the waypoints (it is an optimisation of a route and there is no established standard solution as far as I know although it is being talked about). This is something that should get calculated for every pilot every second of the race in order to award leading points.
There is no standard way to calculate when a pilot crosses a line (way-point or goal) if he is on one side for 1 point at a time and on the other 1 second later when did he/she cross?
When do we say a pilot has landed and should stop getting distance (how do we detect when a pilot stops flying (when not in goal) and starts walking to pack up his/her glider while walking closer to the goal.
How do we define the calculation when someone is in airspace when that airspace has an irregular shape?

@biuti would be able to provide you more details I am sure.

Hi, I sent the comp's task files of FS ,and its scoring results is far with Airscore on my web  http://120.55.53.218/users/task_score_admin/11 If you have time ,please check it, which is correct?  (my web's Admin is : yu0912/peaceylf0912) I want to figure it out very much .
