Isn't it exactly the same "advantage" any motorglider has when they
start the engine far from home and get scored up to that point? Andy's
suggestion will allow pilots to land back home safely few minutes after
sunset if necessary rather then land out to get scored, or fly back
home and don't get scored at all...

Hi Andy,

I must respectfully disagree. If we just use sunset as the end of soaring
flight that gives an unfair advantage to a pilot that is far from home or at
altitude when the sun sets. He/she should have planned ahead and landed on
time.
