@dzee, I believe this is the post the @Kubisuro was referring to:
Also confirm root zone depth and precipitation rate as those will have an impact on the run time. Not sure if there was any cycle and soak time in there as that can lengthen the total time, but not the actual watering time. As mentioned a catch cup test will document the actual precipitation rate and efficiency.
Also, Rachio will assume the water table is empty the first time it runs.
