Clearly I can block more than " just " 2/3rds of the lower grill without overheating or even running any warmer at all.
Just how much extra cooling capacity did mazda provide for this car anyway?

Remember that the fan may be switching on if airflow itself is insufficient. And the fan draws power from the battery and the battery gets power from the alternator, which gets it from your engine. If the fan runs all the time, your aero gains turn into alternator losses. Monitor the radiator fan.
