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: 0.16 ft0.05 m Assuming the level stays the same was off by 0.23 ft0.07 m
Actual level inside our range: 79% of 432 tests; the range is built to catch 8 in 10

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