Winter schedule -Flex Monthly

New to Rachio and have been looking into the scheduling aspect of things. I am going with what Rachio is recommending down here in Texas, warm season grass, however, for winter and when grass is dormant the flex. Monthly schedule doesn’t have it watering as often, which is good, but when it does water, the duration is super high. Does this seem off for winter? Typical temps get to be as low as 32 on morning but warm up to upper 60s-70s. Interested in knowing how other people juggle schedules from summer to winter. Thanks!
