John, a remote finish at high altitude as suggested might be the best option for all US finishes.

The current rule / guidance allows for a potentially unsafe situation. In Mifflin at one mile out (turns out to be the airport edge)at 650 feet you can make a safe approach and landing. You then get a significant penalty. Making a few turns at 650 feet, 1.5 miles out to gain 100 feet has a small time penalty. In the mean time guys a moderate speed are coming through at 750 feet agl to finish. WOW, the safe move of coming in to land has a higher penalty than low thermalling just outside the finish with other gliders trying to get through.
