Watering duration low

Overriding my Flex daily schedule, a 3 day per week water schedule was imposed a while back. To my knowledge, all I changed was the number of days per week. I just looked at zone day end moisture and it was bouncing between 0 & ~0.20 every other day. The run time appears to be capped at 0.36 in per run which apparently is used in 2 days of crop evapotranspiration. Why wouldn’t the run time be longer so as not to go to 0 every day?

Flex Daily will calculate the amount of water to apply at one time based on your soil and crop characteristics. It then varies how often it waters based on moisture level. If there aren’t enough days available to water, it can’t keep up. Rachio recommends allowing it to water 5 or more days per week. 3 won’t work well with it, at least some of the time. If you can’t change the 3 days, you’d be better off with Flex Monthly.
