After 5 days actual Balance = -0.70in; however still shows Balance = 0. Therefore when the Crop Evap decreases and = 0.34in then Balance = 0.01in (actual = -0.69in); the negative is never made up all future additions are based on “0”.
The problem is adjusting for unusual heat wave that takes a good setup under normal conditions to problem when heat comes and you are on vacation or away.
I read the noted discussion and replied there.
Basically suggested calculating the difference between irrigation and evaporation and adding frequency to make up difference, thus Balance is actually “0”.
