Masking Task over Track

Taking what we now know about the tracks and the task, we have times, distances and fractions we’ll need later for the points. So far we have leading, arrival, speed and reach [1] fractions but we still need to look at where pilots landed to have the effort [2] fractions.

If the task is stopped we’ll need some statistics to work out the stopped task validity:

For those landing out, how close or nigh were they to goal, what was their reach? Pilots that arrived at goal have a reach equal to the task distance and are not included in this list of pilots that are nigh.
