Check out Tod's Workshop youtube channel. It's only entertainment, but he has a far more realistic overall testing of arrows' armour-piercing capability.
A lot of the tests are firing perpendicularly at plate armour that's held in front of a hard surface with no gambeson underneath. When you take account of arrows often arriving at a slight angle, and humans are a movable pile of meat covered in thick cloth with plate on top, then the ability to penetrate deep enough to cause a significant wound is reduced.
Never eliminated though!
But if arrows really did pierce plate armour, and I was a knight in a battle then I'd just get myself a 6 foot tall 3 foot wide, heavy wooden shield and hide behind it until I got to close quarters. But the fact is people didn't bother doing this because they found a less cumbersome shield more effective, and that suggests that rich plate-armour-clad knights weren't dying left right and centre from arrow fire.
