You didn't mention the outside temp but, the pressures look ok. What is the fan speed? Any modifications to the system? Max is only a recirculation of air and a shutoff of the heater valve - there is no built-in continuious clutch mode (at low speeds) like some older GM cars, etc. The most air moves across the evaporator at max so a slower cycling would be normal until the low side pressure drops enough - which in your case you should be near refrigerator quality.
