Martin,

Min sink at 60 knots, at 728 lbs? The airspeed seems high. 728 doesn't
seem to be a "wet" weight, as empty is about 553?? Maybe this sink
speed is at gross weight?

I know no more about it than I wrote. I agree with you, though. The
polar looked screwy to me. The min sink looks high and the whole
curve looks too flat. However, the numbers from the Sailplane
Directory look about right.
