It's a great example of the IGC rules issue: Only landout, a few km

330 points. Only finisher, everyone else a few km short: they get 999

US scoring isn't perfect either. It also switches from speed to distance

Heres my current best suggestion:=20

points =3D (day devaluation factor) max ( 1000 x speed / winner's speed,
75=
0 x distance / winner distance)=20

the day devaluation factor doesn't matter here. What matters is speed vs.
d=
istance points. And the key -- they are fixed, irrespective of the number
o=
f landouts.=20

So, only finisher gets 1000, 1 km landout gets 750. Only landout gets

750.

The incentive to be lone wolf goes way up.=20

It works as now if you're really slow. If you are below 75% of the
winner's=
speed, you get 750 points for finishing. You always get the better of
spee=
d and distance.=20

And real simple too. People might (gasp) actually understand their score!

And strategy. No more need for team captains to report landouts to tell

if it's a speed day or distance day.=20

it gets rid of some other IGC idiosyncrasies too, like the occasional
incen=
tive to deliberately land out.=20

Why only get speed points if you finish. I do not see why you shouldn't
earn speed points for going to ground quickly. 100 point finish bonus 500
distance 400 speed
