I think running it once every 2 months is more than enough, so long as the car is actually driven, taken to full temp and kept there for at least 20 minutes.
There is no point in starting it up and idling for 10 minutes, that won't get all the fluids to temp and might also dilute the oil. You'd be better off letting it sit.
There are other precautions to take for long-term storage (battery, tires, etc) but maybe I already said too much.
