First let me say that although these tracks were taken using the 62s, I believe that the sampling would be quite similar in the 60csx, Oregon, Dakota and Colorado as they have the same track sampling options and use the same or a very similar algorithm for that purpose.
The cyan track is set at the most often sampling rate, in auto mode. The red track is set on 1 yard, distance. These were made during a K9 training, searching for divers under water. Each pass was for a different dog. THe difference is obvious, you want precision in the track, chose the sampling rate by distance, 1 yard.
Now I also checked elevation profiles, as elevation was one point that was fixed in the latest beta and on the water, the elevation should be quite the same. Unfortunately, I did not set my GPS to barometric altitude, so that point was not checked. Yet look at the differences:
The cyan track (most often sampling) is on the left, the red track, 1 yard sampling is on the right. The water was not flat, just little waves, no white caps, wind about 5-10mph.
I will stay with my setting for track, 5 yards sampling on land, 1 yard on the water.
