I challenge thee with these questions three:

1. How does sv_skillrating relate to the tiers of the players on the server?

2. Where does the player's 4-sided view pyramid begin within the bounding box? X, Y, Z, in units?

3. What is the size of the player's view in units at a given fov and distance from the object? Size of the object would have to be known, and solving this would probably rely on having the answer to the previous question.
