Default idle rpm

When I first start the car after 24 hrs, the rpm hits past a 1000 which is normal. however, if i drive for 10 mins and put my car in park, the idle rpm is down to 500 or below. Is that normal?

Default No! Engine Idle should never go so low . . .

Warm idle for 12v = 650-750

Warm idle for 30v = 720-820 for FWD ATQ engine; 630-730 for AWD ATQ engine; 740-860 FWD AHA engine; 620-740 AWD AHA engine.

Warm idle for 1.8t = 820-900 (all AEB engines); 740-860 (FWD ATW & AWM engines) 800-920 (AWD ATW & AWM engines)
