I see my TS MPPT 60 do very similiar operation as what you described with your Rouge (Both excellent MPPT controllers). During a typical day we draw a lot of current from the system (I like to think the array is a almost unlimited power source as compared to a battery charger) The air compressor draws 25 amps, the stereo can draw as much as 15 amps, Swamp cooler 3amps, fans and pumps. This time of year the battery bank is almost always topped off at 100% by 11:00am, while the controller continues to switch between it's different operational modes all day long.
I put this document together a year or so back - not much new but might be of interest to others

Nice write up! So many discuss neither spectrum nor temperature.
Worth adding is both angle because of cosine effect, but also agle because of reflection from the glass, which becomes the dominant loss for smooth glass panels at angles where the perpendicular solar output is still in the 25% range. I think people write off the benefits of morning and evening sun far too easily, because their yield with flat smooth glass panels falls off.
