So I just noticed the flex schedule and the moisture level stuff by zone. Looks very interesting in ‘normal’ conditions. We have had a stunning large amount of rain even by local standards (12+ inches since Aug 1st alone). If we get more than 1.5 inches we have street flooding now and ponding in the lawn in low spots and flower beds in a few other places. The water table is most accurately measured in inches below the soil at this writing is less than 1 inch, but was 10 inches after 3 days of no rain… I can actually measure where the Verizon cover plates are as they floated away last week. (So much for not actually being in a flood zone. 
So how does Flex scheduling handle this when the ground is super wet and the water table is very high?
My system has not had to run in 28 days. I doubt it will need to run for another two weeks even if we get no more rain.
I know I can pause it, but I am curious about how Flex handles the moonson season. 
p.s. I am using a PWS and it is mine so I am fairly certain of its accuracy its a high quality unit and if there is some glitch I manually update rainfall etc,.
If the above is not enough as far as a saturation allowance, you can always disable the flex schedule, or using the soil moisture graph fill the tank if you believe that the soil is still saturated.
