Imagine a scoring system where you get 5 minutes added to your time on course for every minute you run your MOP. If you did a 4 knot climb under power for 15 minutes to get home it would cost you about an incremental hour, so you'd only be inclined to use it when the alternative is landing out.


Easy fix. Since the motor is to prevent the land-out score it this way:

Starting Motor = Land Out.

The benefit is avoiding the inconvenience of the land out. Back to the airport in time for BBQ and beer, hope for better the next day.

But you still have the situation where the motor changes the game in various ways.
One is the glider with a motor will do more poorly in weak weather with it's
higher wing loading; another is the pilot can push on during a poor day, knowing
he will achieve the best score he can, and still be able to return home easily -
no lengthy midnight retrieve to leave him too tired to fly the next day.

Longing for "Purity" in the sport is normal, but we don't share a common
definition of "pure": a dedicated 1-26 pilot might think it's a distinction
without a difference when you talk about an 18 meter glider with or without a
motor. For me, a long-time self-launcher owner, a class that uses hybrid scoring
sounds interesting, and I look forward to the experiment.
