The above table is filled out as we get data on how many toads were observed on each day we had volunteers report the toad counts.
Green if: (1) Within 30 toads
Green if: (2) Within 30%
Green if: (3) Actual and predicted toads >= 50
Yellow if: Predicted toads > 100 , actual toads > 30
Red otherwise
These are some of the constants used in the formulas.
There can be more than one set when different sets are being evaluated.
