Kick reception and kick reception range

How do kick reception and kick reception range work? As I saw kick reception higher than 80 helps to recieve kicks without bouncing from the player. And I really do not understand how kick reception works. Do not see any changes training this attribute.
The impact can be quite significant, particularly with kickoff. Problem with our 15s is they usually aren't in the right spot but there is a difference.
Can you tell the exact difference, Black Monks?
They receive kicks better and from a broader distance. Not trying to be smug, but that's the difference.
