Bad distance calculations on Minimum distance

Description (last modified by ste) (diff)
It seems that the software does not take into account the Radii for the task distance calculations, and that´s ok for the turnpoints and also for the speed section, but it´s quite wrong if you substract the start cylinder radii when it´s an exit cylinder around take off.
I nottice this issue looking at the tracks on Santa Cruz Flat Lands as some pilots. The minimum distance for my test was set to 8 km (don´t know what was the minimum distance on the actual meet scoring), and all the days we had an exit start cylinder with 8 km distance radii, meaning that if you got the start you have beaten up the minimum distance for the day. This distance that you get to fly before the actual start of the race should count as flying distance for giving you distance score as it´s quite difficult on some days to even get out of the start circle.
Now, the software is showing that a pilot that flew 7 km past the start cylinder would have only 7 km of scoring distance even when he actually flew 8 km inside the cylinder and 7 outside for a total of 15 km. As the minimum distance is set to 8 km, then a pilot landing right in the paddoc, flying only 1 or 2 km before turning back, staying inside the start cylinder, will score the same as this pilot that actually flew 15 km.
This is definetly a big problem and could represent a big deal on some task.
As an example, we have designed a task for our hang gliding nationals that actually acts like a learning task. Its a 70 km task that has the start cylinder in the middle of it, at 35 km, and it´s an entry start around the goal. This way the first 35 km would be slow and nobody needs to race, so the better pilots can lead and help the not so good pilots all the way into the start cylinder, where the race really start. Doing this, one allows a nice competition teaching, assures that nobody would be flying hard or landing unnecesary on the first half, so the pilots can cover more distance without making too agresive decisions nor flying. Once on the middle of the task the race starts and the fast pilots would break apart. If you do this task with the software working like today, then even after flying for 35 km, you won´t get any distance.
