I know I should let this go....
Smart cycling, unless you switch it off, is always there. It's like gravity. There is no minimum weight at which it works. There is a maximum beyond which you may not be able to escape it and say... jump.
If you are set for a cycle less than the maximum allowed, you will not have a soak cycle. If you are set to water beyond the maximum allowed by smart cycling, you will have a smart cycle mandated soak. The most it will ever be at once is the maximum.
I have to go now, my rain sensor is active.
