Great points! Sometimes the Winter months provide good RAS posts.
(Warning, I don't fly contests but have flown plenty of SLSP and currently own a "pure" sailplane)
Agree that the point of avoiding long retrieves with a late return is good for everyone, whether by the old fashioned chase crew on the entire task or by landing or climbing over a nice safe airport.
Another twist: How do you handicap non-MGs on weak days when a pure sailplane can dump ballast? Getting rid of the engine and fuel weight is impossible in flight.
Possibly you've already found a fair solution?
