The first 9,214 points were used. Those points after that
appeared to be on Hwy 102, so were not used.

Mean Elevation of first 9214 trackpoints = 23 feet
Highest = 54 ft. Lowest = -1 ft. (Range = 55 ft.)

Standard Deviation = 7.2 feet
Mean Deviation from mean = 5.56 feet

Number of Times Elevation Changed:

Count Percent
Less than 1: 5292 57.4 57
By 1 foot: 1501 16.3 74
By 2 feet: 2035 22.1 96
By 3 feet: 257 2.8 99
By 4 feet: 75 0.8 99
By 5 feet: 29 0.3 100
By 6 feet: 12 0.1 100
By 7 feet: 7 0.1 100
By 8 feet: 0 0.0 100
By 9 feet: 0 0.0 100
10 or more: 5 0.1 100

The complete 9,998 points results in:

Mean Elevation = 28 feet
Highest = 231 ft. Lowest = -18 ft. (Range = 249 ft.)

Standard Deviation = 23.90 feet
Mean Deviation from mean = 10.21 feet
