#327 GAP2015: Use distance^2 for LC calculation also in HG comps

Not squared:

Squared:

I had thought that this was the default now with hang gliding competition as it
is with paragliding competitions. But no, it is not optional any more, it is a
required element in GAP 2015. LC is the leading coefficient which is used to
determine the "leading" points.

Joerg Ewald tells me that this has been mandated by CIVL.

You can still use GAP2014 if you don't wish to have this "enhanced" leading
coefficient.

You can see the equations above that make up this leading coefficient here:
http://www.fai.org/downloads/civl/SC7_GAP. Good luck understanding what they
mean.

In paragliding the arrival position points are not used, just these enhanced
leading points, but they seem to be used in the hang gliding version as they
have in the past. Why is not exactly clear.

This is how CIVL works: Two different working groups for hang
gliding and paragliding, and both with very little understanding of scoring
formula details. I managed to push the paragliding group to drop arrival points
(because we’d dropped them in the PWC a while back successfully) when I was a
member of the paragliding group. I have no influence on the hang gliding group,
so even though my recommendation was to do the same there, they didn’t feel like
it.

At least they have now adopted my recommendation of improving leading points by
using distance squared.

This does not have an effect on the amount of available leading points. If no
arrival points are used, these points are added to the speed points bucket
instead.

So, you tell me that you understand hang gliding scoring?
