How well this outlook has done here

We tested the 2-week outlook on past years at this lake, as if made once a week with only what was known that day.

On average it was off by: 0.66 ft0.20 m Assuming the level stays the same was off by 0.84 ft0.26 m
Actual level inside our range: 80% of 430 tests; the range is built to catch 8 in 10
When we said a rise was possible (20–40%): 31% of those 65 times it ended 1 ft0.3 m or more higher

The rise chance uses the same threshold for every lake: 1 ft (0.3048 m).
