Anything less, and you are working with incomplete data.
The heating rule also applies for oil changes. The oil has to be warm to drain also.
Anything less, and you won't be able to clear the engine & reservoir(s) out completely.

Yes, car properly warmed and on a level surface. Allow to idle (around 750-900 rpm) for 30-60 seconds prior to pulling the dipstick. Wipe dipstick, dip and read.
FWIW, I have not noted a significant volume difference between draining the oil hot or cold. It just takes longer when it is cold.
