Great, well then I will continue to leave it alone except for monitoring pressures - and only "mess with it" if the pressures drop or ac stops cooling. Thanks!

another cooling change could be the outside temp, or your aux fan working all of a sudden.
if it's significantly cooler outside, your system will work better. oddly also if it was cool outside when you checked it the first time, and now it's warmer it could be working better too. if the pressures are low, and it's cool outside, the unit could be working SO well, you could be frosting the indoor coil, and blocking off airflow. warmer ambient outside temps, could keep the pressures up enough to keep the coil from freezing.
