..I just wonder if my 3rds would have beed 2nd's,..and the one 2nd a first..
Actually you may have done worse. You stated that they were not using the wind strength factoring so your actual DPN should have been 66.7 rather than 69.
Hey Lance, it's a Euro-spec I-17, w/the short aluminum mast and no kite - the 4-5 numbers are around 73.2, and D-PN is still 73.0.
