Gave the OWS profile a try today. At first the total seemed long, but then looking at it online, I realized that I didn't turn it off right away when I got out and it added a bunch of distance when I really didn't go very far out of the water. Odd. If I subtract that extra distance (by tracking my GPS route online to see where I got out), it appears to be pretty accurate. It was only maybe a minute, so I'm not sure what happened there.
Will try again and attempt to turn off at the right time to see what happens.
