> That’s why I’m suggesting there must be something that guides the idea that hit position changes the angle.

Fun. The guiding principle for all games should be: is it fun?

The reason the position of impact determines the angle is because it’s more fun, Not because it’s realistic.

Realism is rarely fun.

It’s a game, not a physics simulation.

Edit:

Additionally, if you only implement perfect reflection and have a rectangular arena, then the only bounce angles that can occur are the initial ball angle A and 90 - A on the top and bottom sides. That’s not fun.
