It is my habit to remove the drain bolt, start the flow, then remove the filler cap. On most vehicles, the flow will increase when the filler cap is removed.
Then I find something else to do and let it drain to the last drop.
If I recall correctly, my Moto Guzzi V7II did not like to drain much until the filler cap was removed and it had two drain bolts for the engine.
