:dunno: Does anyone know how they determine the official yardage for the 1 hour swim. My entry form recorded a total of XX87 yards completed and adjusted downward to the nearest 5 yard which was XX85 yards but I only recieved credit for XX70 yards. I completed my turn at the 75 yards and swam a stroke or two and then the horn sounded. This was my first 1 hour swim and I did it with a group of 24 other swimmers. I am not complaining...I just don't understand why the yardage was adjusted down. If we did something wrong, and we know what it was, we can correct it next time.
